Technical field
The present invention relates to medicine and food technology field, specifically relating to a kind of Chinese medicine extract---bioactive natural product is used to prepare the purposes of antifungal, antitumor and anti-angiogenic property senile dementia product, more particularly relate to a kind of marine fungi extract---bioactive natural product B, promptly 4,6-Dihydroxy-3-methylene-10-propenyl-2-oxa-spiro[4,5] dec-8-ene-1,7-dione is used to prepare the purposes of antifungal, antitumor and anti-angiogenic property senile dementia product.
Background technology
(1) research overview of marine fungi
1, general introduction
Marine microorganism is survived in special biotic environment with it and is had the great potential that produces the novel bioactive material.During the last ten years several, the secondary metabolite of nearly 600 novel structures of isolation identification from marine fungi, chemical compound lot has shown good antitumor, antibiotic and antiviral activity; Other has some compound exhibits to go out unique physiologically active, as anti-senile dementia.
Therefore, Marine microorganism is a research focus in recent years.---especially there is the microorganism of relations such as symbiosis or parasitism in those with marine animal or sea-plant---can produce the unique also metabolite of the strong physiologically active of tool of structure more and more to studies show that Marine microorganism.And the Marine microorganism breeding is fast, can utilize modern microbial technique, and the large-scale industry fermentation has broad application prospects.Scientists is estimated, is developed new marine drug and will place hope on this new field of Marine microorganism.
2, marine fungi
Marine fungi (Marine Fungi) is to live in can form spore and the microorganism of eucaryon structure is arranged in the ocean, is the fungus monoid that can breed and finish life cycle in sea water, can well grow on sea water medium again, claims the sea water fungus again.That is: have the eucaryon structure, can form marine organisms (1. J.Kohlmeyerand E.Kohlmeyer, Marine Mycology, Academic Press, New York, 1979 of spore, the saprophytic or parasitic life of battalion; 2. T.W.Johnson, F.K.Sparrow, Fungi in Oceans and Estuaries, J.Cramer, Weinheim, 1961).
Marine fungi is generally mycelioid and many cells, has only yeast that unicellular appearance was arranged in the stage of development.Nutritional mode except that Acarasiales for the formula of ingesting, mostly be absorption.Some derive from the ocean and can grow and the beginner in the habitat, ocean, are called the obligate marine fungi; Other derive from land or fresh water, but can grow and the beginner in the habitat, ocean, are called facultative marine fungi.
They adapt to the acid-base value of sea water, and the osmophilic strain ability is stronger, and great majority are dwelt and lived in certain basic thing, for example parasitize Sargassum and marine animal, and are perhaps saprophytic on the timber that soaks in sea water; The minority free living for example can be grown in saliniferous wetland and the evergreen chinquapin marsh.Therefore, the distribution of fungus in the ocean depends primarily on host's distribution.
French M.C.de Deere waited approximately and at first find marine fungi from zostera marina 1869 brief histories of research.1934, F.K. Si Paro was studied the algal fungi class in Denmark marine site.Nineteen forty-four, E.S. Ba Hong and D.H. woods moral are delivered the paper of the living fungus of research ocean wood.1961, " ocean and the river mouth fungus " of T.W. Claes Johanson and F.K. Si Paro discussed classification and the biological characteristics of marine fungi.E.B.G. Jones chief editor's in 1978 " aquatic fungi is learned progress " discussed the progress of marine fungi form, physiology and ecological aspect." marine mycology-higher fungus " of J. Cole mayers in 1979 etc. systematically discussed the achievement in research of high marine fungi.
Classification is present, and most scholars think that fungus should independently become boundary (King-dom mycota).But, go back the scheme that neither one is comparatively generally acknowledged so far to the division of affiliated door, guiding principle etc.According to existing record, marine fungi is 500 kinds of less thaies still, only are equivalent to 1% of the true strain number in land (about 50,000 kinds).Comprise 209 kinds of thread high marine fungis, 177 kinds of marine yeast mushrooms, low marine fungi algal fungi class (Phycomycetes) about 70 kinds that wait.In high marine fungi, 56 kinds of 149 kinds of ascomycetes (Ascomycetes), 4 kinds of basidiomycetes (Basidiomycetes) and Fungi Imperfectis (Deuteromycetes) are arranged.
Marine fungi can be divided into Sargassum bacterial parasite, the saprophytic sea water bacterium of timber and spoon sporangiocyst order 3 classes:
1. the parasitic kind on the Sargassum has knee Pseudomonas, genus thraustochytrium, chain Chytridium, Saprolegnia, hat spore shell to belong to, belong to and the mould genus of change spore etc. every sorosphere shell genuss, ball seat Pseudomonas, proximal branch chain spore;
2. the saprophytic sea water bacterium of common timber has hat spore shell to belong to, the shell genus is given birth in the sea, wood is given birth to shell genus, oar spore shell genus, Leucosporidium, plan Corallium Japonicum Kishinouye spore genus, Humicola and do not have stalk spore genus etc.;
3. spoon sporangiocyst order colonizes on the red algae, and the ability of decomposing halogen is stronger.The evidence that provides mushroom to originate from red algae is provided the spoon sporangiocyst, and the someone thinks that it is that timber living ascomycetous direct ancestors in the sea water.
The distribution marine fungi is widely distributed, to the deep-sea, to halmeic deposit, its member is arranged all from the sandy beach, shallow sea from Intertidal zone high-water mark or river mouth.Marine yeast and lower fungus grow nonparasitically upon another plant on plankton and animal body, thereby at big midocean distribution are arranged also; The growth of high marine fungi requires suitable basic thing as dwelling living place, therefore focuses mostly on and is distributed in littoral sea.Because the saprophytic or parasitic life of marine fungi battalion is so the characteristics of its geographical distribution are the geographic ranges that depends on the host.But the concentration of dissolved oxygen and sea water water temperature in the sea water also are to influence marine fungi to exist and the important factor that develops.Nearly all fungus all can be in less than sea water grows under the condition of sodium oxide concentration, so salt tolerance can not be as the sign of distinguishing marine fungi and land fungus.
Derive from the depth of water and surpass fungus in 500 meters marine environment, have the ability that adapts to high pressure, low temperature and grow significantly.The deep-sea fungus of now knowing has only 5 kinds, and the maximum water depth of collected specimens is 5315 meters.
The most of marine fungis dependences of ecological habit are dwelt certain basic thing and are lived, and have only the minority fungus not rely on basic thing and free living.
According to its living habit of dwelling, marine fungi can be divided into 5 kinds of basic ecotypes:
1. wooden living fungus.The widest with the distribution at most higher fungus of quantity in ocean water body, battalion's saprogenesis, kind decomposition of cellulose.It is more extensive to distribute in tropical marine site and neritic environment.Known have 76 kinds of ascomycetes, 29 kinds of Fungi Imperfectis, 2 kinds of basidiomycetes.
One class quantity at most, the widest high marine fungi distributes.Can decompose timber and other fibrous matters consumingly.They are extensive than temperate zone and polar region in the distribution in tropical marine site, and are extensive than the deep-sea in the distribution of neritic environment.In the living fungus of known 107 kinds of oceans wood, ascomycetes accounts for 76 kinds, and Fungi Imperfecti accounts for 29 kinds, and basidiomycetes has only 2 kinds.
2. parasitic frond fungus.Account for 1/3 of marine fungi kind number, wherein in the majority with ascomycetes.Types such as saprophytic, parasitism and symbiosis are arranged.
In marine fungi, there are 1/3 kind and algae to be related approximately, wherein in the majority with ascomycetes.Types such as saprophytic, parasitism and symbiosis are arranged.The distribution of different Sargassums can directly influence the distribution of such fungus, as in the Sargasso Sea of the North Atlantic Ocean, kind of fungus and quantity find seldom also by the Sargassum of fungal infection that all seldom this is because Alga Sgrgassi Enerves (Sar as-sum spp) has the tannin material of antibacterial action.In general, rot saccharomycetic quantity on the Sargassum to be higher than on the frond alive and sea water in quantity; Be attached to the yeast quantity on red algae and the chlorella, be higher than on the Brown algae.Because the excretory phenolic material mass-energy of Brown algae suppresses the growth of marine fungi.Some marine fungis combine the coalition that forms obligate symbiosis with specific Sargassum, be the ocean lichens.
3. mangrove fungi.Mostly be saprophytic bacteria, wherein ascomycetes is 23 kinds, 17 kinds of Fungi Imperfectis, 2 kinds of basidiomycetes.
Rhizophora apiculata Blume is the plant (show woods biome) of tropical and subtropical zone Intertidal zone salt moorland.The marine fungi that gives birth in Rhizophora apiculata Blume that dwells is saprophytic bacteria mostly, 23 kinds of ascomycetes is wherein arranged, 17 kinds of Fungi Imperfectis, 2 kinds of basidiomycetes.Be immersed in that Rhizophora apiculata Blume pivot in the sea water is done, after the epidermis of branch and root is perforated animal, stormy waves or artificial damage, very easily invaded and cause rotten by fungus.But be embedded in the root in the mud, then be not subject to the fungus infringement.Marine fungi can be decomposed the Rhizophora apiculata Blume blade, for the ocean provides a large amount of organic debris.
4. zostera marina fungus.Quantity seldom, many perch are in leaf portion.
Negligible amounts, wherein the fungus of the perch leaf portion root person of dwelling is many.Contain the material of tannin and other inhibition biological growths in the zostera marina root, have only those marine fungis that can resist this class material could on the zostera marina root, adapt to growth.
5. zooparasite body fungus.Only limit colonizes in ectoskeleton and shell portion place.
Being confined to colonize in ectoskeleton, shell etc. locates.In the processes such as cellulose, chitin, protein and calcium carbonate of marine fungi in decomposing animal body, play an important role.Low marine fungi such as grade is the important pathogenic bacteria that causes marine fishes and invertebrates disease.
Marine fungi often has following characteristics:
If 1. belong to Ascomycotina, then be mainly the member of the gang pyrenomycetes of decomposition of cellulose vigor, shell of ascus black, ascospore often have the appendage that contains acidic polysaccharose, help sticking on the new substrate.Usually no conidium from generation to generation.
2. if imperfect fungi, then spore is a roof spore type, mostly is dark-coloured.
Marine fungi and marine bacteria are all participated in the regenerative process of organic decomposition in ocean and inorganic nutrients thing, constantly provide effective nutrition for sea-plant; But marine fungi is bacterial parasite and the pathogenic bacterium of marine animal, and the sea-plant that can make that has is caused a disease, even the wooden structures in the port equipment is rotted; Some marine fungi can be destroyed Polymer Synthesizing materials such as polyurethanes.
The meaning marine fungi is the same with marine bacteria, participates in the decomposition of ocean organic substance and the regenerative process of inorganic nutrients thing, for sea-plant constantly provides effective nutrition, occupies critical positions in marine food chain.Particularly fungal mycelium in marine sediment and yeast thalline provide the source of bait for ocean protozoacide, zoobenthos etc.Some marine fungi can produce antibiotics and other biological active substanceies, is the huge treasure-house of new drug development, and is also significant in ecology and application facet, and the pollutant as in the degraded marine environment promote ocean self-cleaning etc.; Utilize marine fungi processing Testa Tritici, bagasse, Caulis et Folium Oryzae etc., make cheap microorganism crumb mixture, as the feedstuff in the aquaculture.
Marine fungi is bacterial parasite and the pathogenic bacterium of some marine animal, once sustains losses severely because of the infringement of fungus as U.S. Concha Ostreae production area.Can cause the disease of some sea-plant, once seriously be infected by net Acarasiales genus fungus as the zostera marina in the North Atlantic Ocean, pacific rim and Europe.The living fungus of ocean wood can rot wooden structures and other fibrous materials in port facilities, breakwater and the weir dike.Some marine fungi can be destroyed the synthetic material in the sea water, and can expanding after being penetrated by them as polyurethane material, it is bad to split.
3, the chemical constitution of bioactive natural product B and preparation method
The metabolite B of marine fungi Massarina tunicata obtains for therefrom separating in the marine fungi of state sea first.Activated product B and mannitol all have higher content in the fungus, if its condition of culture is carried out more deep research, Massarina tunicata can be developed as a kind of resource bacterium, further strengthen the research aspect raising immunologic function, anticancer, the anti-ageing effect of waiting for a long time.
In the metabolite of marine fungi #K26, the choline sulfuric ester obtains for separating from southern China sea marine fungi first; 3,4, the 5-trihydroxybenzoic acid is to find from marine fungi first.Choline sulfuric ester and mannitol all have higher content among the fungus #K26, if its condition of culture is carried out more deep research, #K26 can be developed as a kind of resource bacterium.The choline sulfuric ester (is called for short: COS) extensively be present in occurring in nature, play the part of important role aspect the microorganism conversion of its sulfur in soil.Various plants, soil fungi and antibacterial can both utilize choline and PA (3 '-phosphoadenosine-5 '-phosphosulphate) as substrate, synthetic COS under sulfur conversion enzyme catalysis, hydrolysis can take place in COS under the effect of choline sulfuric ester hydrolytic enzyme on the other hand, becomes one of source of interior choline of organism and sulfate group.Key player of the row of COS is as the impermeabilisation chemical compound.3,4,5-trihydroxybenzoic acid (being gallic acid) is a kind of polyphenol compound, owing in the molecule a certain amount of ROH base is arranged, can be formed with the hydroperoxyl radical (H) of antioxidation, and superoxide anion (O is arranged 2 -) and the activity of hydroxyl radical free radical free radicals such as (OH), thereby protective tissue is avoided the infringement of Oxidation, and improve immunologic function, anticancer, the anti-ageing effect of waiting for a long time.
By to marine fungi Massarina sp., the further investigation of strain CNT-016, found at present spiro lactone chemical compound 6-epi-5 '-hydroxy-mycosporulone (referring to: M.A.Abdel-Wahab et al./Phytochemistry 68 (2007) 1212-1218), but do not carry out deep bioactivity research as yet, the chemical compound that research of the present invention relates to has similar parent nucleus with it, and has carried out the active and anti-angiogenic property senile dementia research of antifungal and antitumor.
(2) extraction separation method of conventional effective ingredient
1, solvent extraction method
(1) principle: solvent extraction method is according to the extract raw material dissolution properties of various compositions in solvent in the Chinese herbal medicine for example, select for use the active component dissolubility big, to not needing the little solvent of stripping composition dissolubility, and the method that effective ingredient is dissolved out in the medical material tissue.When solvent is added to extract raw material (Chinese herbal medicine for example, suitably pulverizing) in the time of in, solvent is owing to diffusion, osmosis penetrate in the cell by cell wall gradually, dissolved solable matter, and cause concentration difference inside and outside the cell, so intracellular concentrated solution is constantly to external diffusion, solvent constantly enters in the medical material histiocyte again, so repeatedly come and go, when solution concentration reaches dynamic equilibrium inside and outside cell, this saturated solution is leached, continue repeatedly to add novel solvent, just can be bordering on complete stripping or the stripping of big portion to desirable ingredients.The dissolubility of extract material composition in solvent is directly relevant with solvent property.Solvent can be divided into hydrophilic organic solvent and lipotropy organic solvent, and dissolved material also has hydrophilic and lipophilic difference.Hydrophilic radical is many in the organic compound molecule structure, and its polarity is negligent of oil greatly; The hydrophilic radical that has is few, and its polarity is little and be negligent of water.The character of each kind solvent, equally also relevant with its molecular structure.Like this, the inventor just can remove to estimate their this type of character and the solvent of selecting for use by to for example medicinal herb components structural analysis of extract raw material.Generally speaking,, bigger dissolubility will be arranged therein, i.e. the rule of so-called " similar mixing " as long as this character of the hydrophilic of extract material composition and lipotropy and solvent is suitable.This is to select appropriate solvent to extract one of foundation of required composition in the extract raw material.
(2) choice of Solvent: the key of utilization solvent extraction method is to select appropriate solvent.Solvent is selected suitably, just can be more successfully the composition of needs be extracted.Selective solvent will be noted following 3 points: 1. solvent is big to the effective ingredient dissolubility, and is little to the impurity dissolubility; 2. solvent can not play chemical change with the composition of Chinese medicine; 3. solvent want economical, be easy to get, safe in utilization etc.Common extraction solvent can be divided into following three classes:
1. water: water is a kind of strong polar solvent.Hydrophilic composition in the extract raw material can both be gone out by water-soluble as the not too big polysaccharide of inorganic salt, saccharide, molecule, tannin, aminoacid, protein, acylate, alkaloid salt and glycoside etc.In order to increase the dissolubility of some composition, also often adopt sour water and aqueous alkali as extracting solvent.
Ethanol), methanol (but also claims: another name for), acetone etc., the most frequently used with ethanol 2. hydrophilic organic solvent: just general said and the miscible organic solvent of water (claim not only: as ethanol.Alcoholic acid solubility property is relatively good, and is stronger to the penetration capacity of extract raw cell.Outside hydrophilic composition isolating protein, phlegmatic temperament, pectin, starch and the part polysaccharide etc., big multipotency dissolves in ethanol.Be insoluble in the low-polarity component of water, the dissolubility in ethanol is also bigger.Can also adopt Different concentrations of alcohol to extract according to the character that is extracted material.More less than water consumption with ethanol extraction, extraction time is short, and it is also few to dissolve the water-solubility impurity that.Ethanol is organic solvent, though inflammable, toxicity is little, low price, and convenient sources has a locking equipment can reclaim repeatedly and use, and alcoholic acid extracting solution is difficult for moldy metamorphism.Owing to these reasons, be one of always the most frequently used method with the method for ethanol extraction.The character of methanol is similar with ethanol, boiling point lower (64 ℃), but toxic, should note during use.
3. lipophilic organic solvent: the organic solvent that just general said and water can not be miscible, as petroleum ether, benzene, chloroform, ether, ethyl acetate, dichloroethanes etc.These choice of Solvent performances are strong, can not or be not easy to propose hydrophilic impurities.But this kind solvent volatility is big, how inflammable (except the chloroform), generally poisonous, price is more expensive, equipment requirements is higher, and they penetrate plant tissue ability a little less than, often need to extract repeatedly for a long time and could extract fully.If contain more water in the medical material, just be difficult to leach its effective ingredient with this kind solvent, therefore, when extracting the extract raw material in a large number, directly using this kind solvent has certain limitation.
(3) extracting method: with solvent extraction extract material composition, infusion process commonly used, percolation, decocting method, reflux extraction and continuous backflow extraction method etc.Simultaneously, factors such as the degree of grinding of raw material, extraction time, extraction temperature, appointed condition also can both influence extraction efficiency, must take in.
1. (be called for short: infusion process): the dipping genealogy of law is packed extract material powder or fragment in the proper container, adds The suitable solvent (as ethanol, rare alcohol or water), and the dipping medical material is with the stripping method of composition wherein to flood extraction method.This law is relatively simple, but leaching rate is relatively poor, and is solvent as water, and the easy moldy metamorphism of its extracting solution must note adding suitable preservatives.
2. (be called for short: percolation): percolation is that extract raw material powder art is contained in the percolator to the percolation extraction method, constantly adds novel solvent, makes it penetrate medical material, flows out a kind of leaching method of leachate from top to bottom from the percolator bottom.When moving down when solvent infilters medicated powder, stripping composition proportion strengthens, its position is just replaced in the solution on upper strata or rare immersion, causes good concentration difference, and diffusion energy is carried out preferably, so leaching effect is better than infusion process.But should control flow velocity, in oozing transient, on powder, replenish novel solvent at any time, make till effective ingredient fully leaches in the medical material.Maybe extremely shallow or when oozing the volume that gushes liquid and being equivalent to heavy 10 times of crude drug when oozing the dropping liquid color, just can think and extract basically fully.The rare leachate that often will collect in mass production is as the usefulness of the solvent of another batch new raw material.
3. (be called for short: decocting method): decocting method is traditional leaching method that China uses the earliest to decoct extraction method.Used container is generally pottery, sand jar or copper, enamel ware, should not use iron pan, in order to avoid the medicinal liquid variable color.Preferably stir often during straight fire heating, in order to avoid that local medical material is heated is too high, burnt easily the paste.Big reaction pot, big copper pot, barrel are adopted in the pharmaceutical factory that steam-heating apparatus is arranged more, or feed Steam Heating in the pond of cement block.It is interconnection by pipeline also several can be decocted device, fries in shallow oil continuously and soaks.
4. heating and refluxing extraction method: use the organic solvent heating extraction, need to adopt the reflux device, in order to avoid the solvent evaporates loss.When operating in a small amount, can on round-bottomed flask, connect reflux condenser.The powder charge material is about 20%~60% of capacity in the bottle, and solvent soaked the about 1~2cm in medical material surface.Reflux in water-bath, the general maintenance, seethed with excitement 3~6 hours, puts cold filtration, and solubilizer in medicinal residues is made second and third time reflux and is made an appointment with half an hour respectively again, or to carrying till the most effective ingredient substantially.This method extraction efficiency adopts continuous extractions than the cold-maceration height more in the mass production.
5. continuous backflow extraction method: use volatile organic solvent and extract the extract material effective component, no matter small test or large-scale production, all with continuous extraction for well, and need with quantity of solvent lessly, the extraction composition is also more complete.Laboratory fat-extraction device commonly used or title apparatus,Soxhlet's.Continuous extraction generally needs a few hours could extract fully.It is longer to extract the composition heated time, and the labile composition of case of thermal instability should not adopt this method.
2, separation and purification process:
Said extracted method resulting extract raw material extracting solution or extract remain mixture, need further remove impurity, separate and make with extra care.
(1) solvent segregation: generally be with above-mentioned total extract, select three for use, the solvent of four kind of opposed polarity, by low polarity to high polarity proceed step by step extraction separation.Aqueous extract or ethanol extract often are jelly, be difficult to be dispersed in the low polar solvent, so can not extract fully, can admix an amount of inert filler, as kieselguhr or fiber powder etc., low temperature or natural drying then, after the pulverizing, to select for use solvent to extract successively, make each constituent in the total extract again, obtain according to the difference of its dissolubility in the opposed polarity solvent separating.Utilize the extract material chemical component, the dissolubility in the opposed polarity solvent carries out separation and purification, is the most frequently used method.
(2) solvent extraction:
1. extraction: the solvent extraction extraction is called for short extraction again, is to utilize the difference of each composition partition coefficient in two kinds of immiscible solvents in the mixture and reach isolating method.If each composition partition coefficient in solvent differs big more during extraction, then separation efficiency is high more; If the effective ingredient in aqueous extract is lipophilic material, the general lipotropy organic solvent of using more, extract as benzene, chloroform or ether, if effective ingredient is to be partial to hydrophilic material, indissoluble is separated in lipophilic solvent, just need use weak lipophilic solvent, for example ethyl acetate, butanols etc. instead.Can also in chloroform, ether, add an amount of ethanol or methanol to increase its hydrophilic.When extracting flavones ingredient, how to extract with ethyl acetate and water.Then multiselect n-butyl alcohol, isoamyl alcohol and water extract to extract the strong saponin of hydrophilic.But, the common organic solvents hydrophilic is big more, and the effect of doing extraction with water is just bad more, and is because more hydrophilic impurities is followed, very big to the further refining influence of effective ingredient.
2. counter current continuous extraction method: be a kind of successive solvent extraction.Its device can have one, several or more extracting tube.Fill the contact surface during with increase solvent extraction in the pipe with little porcelain circle or little rustless steel wire ring.If a kind of infusion of extract raw material need extract with the benzene lighter than water, ethyl acetate etc., then need water extracting liquid is contained in the extracting tube, and benzene, ethyl acetate are stored in the high-level container.Extract whether complete, but sample thief is analysed with thin layer chromatography, ply of paper and chromogenic reaction or precipitation are checked.
3. counter-current distribution method: counter-current distribution method claims CCD method, counter-current distribution or countercurrent distribution again.Counter-current distribution method is consistent with solvent counter-current extraction principle, but the application of sample amount is certain, and continuous in the solvent of a constant volume, reaches the separation of mixture through repeatedly being shifted the extraction distribution.
4. drop counter-current distribution method: the drop counter-current distribution method claims the droplet countercurrent chromatography method again.Be improved solvent extraction on the counter-current distribution method basis in recent years.To the same substantially counter-current distribution method of the selection of solvent system, but requirement can be separated at short notice, and can generate effective drop.Because mobile phase forms drop, contacting effectively with immobile phase in thin distribution extracting tube, rubbing constantly forms new surface, promotes the distribution of solute in solvent, so its separating effect is often good than counter-current distribution method.
(3) macroporous adsorbent resin method: macroporous adsorbent resin is a class organic polymer adsorbent that grows up the sixties in 20th century, have the good adsorption performance, be applied to the development of the extraction separation and the new Chinese medicine of extract material chemical component surplus in the of nearly ten over year gradually.
Macroporous adsorbent resin is for absorption and screen the parting material that principle combines.Its adsorptivity is because the result of Van der Waals force or generation hydrogen bond.The screening principle is because itself cellular structure determines.Because absorption and screening principle, organic compound separates through certain solvent elution on macroporous adsorbent resin according to the difference of absorption affinity and the size of molecular weight.This make organic compound especially the purification of water soluble compound simplified greatly.The skeleton of macroporous adsorbent resin is generated by styrene and divinylbenzene polycondensation, because the adding of modifier, the polarity of macroporous adsorbent resin changes, and according to the surface nature of resin, that adsorbent resin generally is divided into is nonpolar, Semi-polarity and polarity three classes.
Nonpolar adsorption resin be by the very little monomer-polymer of dipole moment make not with the adsorbent resin of any functional group.Typical example is the adsorbent resin of styrene-divinylbenzene system, as D101, XAD-1, DiaionHP-10 macroporous adsorbent resin.
The Semi-polarity adsorbent resin refers to contain the adsorbent resin of ester group, as an acrylate or a crosslinked analog copolymer such as methacrylate and double methyl methacrylate.It is on the basis of nonpolar macroporous adsorption resin, adds acrylic acid methyl ester. or acrylonitrile polycondensation and forms, as the frequent AB-8 macroporous adsorbent resin that uses of China China.
Polar Adsorbent Resin is meant that amide-containing, itrile group, phenolic hydroxyl group etc. are nitrogenous, the adsorbent resin of oxygen, sulfur polar functionalities base.In addition, sometimes the ion exchange resin of ligand groups such as nitrogenous, oxygen, sulfur is called strong Polar Adsorbent Resin, the boundary of strong Polar Adsorbent Resin and ion exchange resin is difficult to difference.Polar macroporous adsorption resin can be formed by methyl methacrylate, acrylamide or the polycondensation of sulfoxide class, as the Diaion HP 2MG of Mitsubishi chemical industry, the XAD-10 of U.S. Rohm-hass company, XAD-9 macroporous adsorbent resin.
Compare with other adsorbent with active carbon, macroporous adsorbent resin has a lot of advantages, and is higher as the adsorptive selectivity to certain material; Physical and chemical stability and mechanical strength are better; Description is more, can change resin physics or chemical constitution as required; Adsorbent resin is generally spherical particle, and fluid resistance is less or the like.Thereby be widely used in chemical industry, medicine and other fields, more and more about the applied research report of macroporous adsorbent resin in natural product extraction is separated in recent years.Macroporous adsorbent resin all has certain adsorption to extract material chemical component such as alkaloid, flavone, saponin, coumarin and some other glycoside compositions.Absorbability to sugar is very poor, and is stronger to the absorbability of pigment.
(4) sedimentation method: be in extract raw material extracting solution, to add some reagent to make the generation precipitation, with the method that obtains effective ingredient or remove impurity.As lead salt precipitation: lead salt precipitation is one of classical way of separating some extract material composition.Because lead acetate and Lead monosubacetate in water and alcoholic solution, can generate the lead salt or the complex salt precipitation of indissoluble with multiple extract material composition, so can utilize this character that effective ingredient is separated with impurity.Then lead salt precipitation is suspended in the novel solvent, passes to hydrogen sulfide gas, make and decompose and transfer insoluble vulcanized lead to and precipitate.
(5) salting out method: salting out method is in the water extract of extract raw material, adds inorganic salt to finite concentration, or the state that reaches capacity, and can make the dissolubility of some composition in water reduce precipitation and separate out, and separate with the big impurity of water solublity.Be commonly used for the inorganic salt of saltouing sodium chloride, sodium sulfate, magnesium sulfate, ammonium sulfate etc. are arranged.
(6) dialysis: dialysis is to utilize small-molecule substance can pass through semipermeable membrane in solution, and macromolecular substances can not reach isolating method by the character of semipermeable membrane.Otherwise also macromolecular impurity can be stayed in the semipermeable membrane, and micromolecular material is entered in the outer solution of film by semipermeable membrane, and separation and purification in addition.
(7) crystallization, recrystallization and Steppecd crystallization: identify the extract material chemical component, study its chemical constitution, must at first the extract material composition be prepared into the pure product of monomer.At normal temperatures, the character of material own is the chemical compound of liquid, can carry out separation and purification with fractionating process or chromatography respectively.In general, the extract material chemical component is solid material at normal temperatures mostly, all has the general character of crystalline solid, can reach the purpose of separation and purification according to the difference of dissolubility with crystallization process.
3, conventional drying method
(1) vacuum drying: be based on such ultimate principle: water saturation vapour pressure and temperature are closely related, under vacuum state, the boiling point lowering of water, i.e. operation operation at low temperatures just under vacuum, can avoid the destruction of nutritional labeling such as vitamin etc. at high temperature, improve rate of drying simultaneously.Vacuum drying is widely used in industries such as food, pharmacy, chemical industry, and China also develops and introduced various vacuum dryers, and its version is varied.Form commonly used mainly contains box type vacuum exsiccator, bipyramid formula vacuum desiccator, belt vacuum desiccator etc.These traditional Minton dryers mainly adopt heating such as hot blast, steam or electricity, utilize conduction of heat, convection current or radiation theory that heat is passed to material inside from the outside.It is low that vacuum drying has a baking temperature, and anoxia relatively in the hothouse can be avoided fat oxidation, and series of advantages such as pigment brown stain are suitable for the drying of heat sensitivity food material, and equipment cost, dry expense are also relatively low in addition.
(2) spray drying: be that fluidization technique is used for the exsiccant a kind of method of liquid material.Because of being wink-dry, be specially adapted to heat sensitive material, so the products obtained therefrom quality is good, keep original color, smell and taste, and easily dissolving.The research that utilizes spray drying to prepare microcapsule is carried out, it is that heart material is suspended in the solution of dress material, through centrifugal atomizer it is sprayed in the thermal current, the product of gained is the microcapsule that dress material bag heart material forms, this microcapsule powder can be used in direct compression, also can prepare capsule, syrup or suspensoid.
(3) lyophilization: be that the dry liquid material is frozen into solid, under the low-temperature reduced-pressure condition, utilize the distillation performance of icing, make the low-temperature material dehydration and reach exsiccant a kind of method.Because material is dry under high vacuum and cryogenic conditions, so the drying of some extremely thermo-labile article is well suited for.Wang Dalin has reported a kind of spraying ventilation lyophilizing new technique, be to utilize cold air or nitrogen as medium, the scars of flowing through rapidly make water sublimate, the product microgranule that makes of spraying lyophilizing is little, fast drying, time are short, evenly, good fluidity, and the good instant capacity of tool.In recent years, plaster material and the exsiccant research of sticky material have been obtained bigger progress, fluidization technology, spraying technique, inert carrier technology then grow up on this research basis.Rotatingandflashstreamingdrier, thermojet pneumatic drier, inert carrier drying machine all are fit to the drying of heat sensitive material and plaster material.These new achievements in research are used for Chinese medicine preparation production, with improving the technical merit of Chinese medicine processing greatly, enhance productivity.
(4) far infrared heating drying method: be a new dry technology, its drying principles is to change electric energy into far infrared radiation, thereby by the molecule absorption of medical material, produce resonance, cause the vibration and the rotation of molecule and atom, cause the object heating,, finally reach exsiccant purpose through thermal diffusion, evaporation and chemical change.Far-infrared ray drying can be saved electric energy 20%~50%, and effect is better.
(5) micro-wave drying method: be the new technique that develops rapidly a sixties in 20th century, microwave drying is actually by eddy-current heating and medium heating, make moisture and fat in the thing that is dried absorb microwave energy to some extent, thereby and it is changed into heat reach exsiccant purpose.But microwave drying killing microorganisms and mycete, and has disinfective action.The microwave heating installation of China's production at present has 915mhz and two frequencies of 2450mhz.
(3) research overview of vascular dementia
Dull-witted (Dementia) is the acquired and persistence disturbance of intelligence syndrome that produces owing to disordered brain function, and disturbance of intelligence comprises that in various degree memory, language, visual space function, abnormality of personality and cognitive competence reduce.
Dull-witted main type is to comprise vascular dementia (vascular dementia, or claim: the vascular senile dementia, be called for short: VD), the senile dementia in the senile dementia (Alzheimer ' s Disease, or claim: alzheimer's disease, or claim: Alzheimer's disease, be called for short: AD) etc.
Senile dementia comprises senile dementia, multiple infraction type dementia (Multimfarct Dementia), alcoholic dementia disease (Alcoholic Dementia) and normal brain activity setting-out brain disease (Normal Pressure Hychocephalus), and wherein senile dementia is the main type in the senile dementia.Because AD falls ill in old people more than 60 years old well, so custom is called as degenerative brain disorder.
Vascular dementia is caused by cerebrovascular, is mainly caused by cerebral hypoxia ischemia.Common clinically multi-infarct dementia, large tracts of land cerebral infarction dementia, thalamic dementia and types such as concurrent dementia of hemorrhagic cerebrovaseular and Combination dementia.Clinical manifestation is depression, delirium, aphasia etc.Pathological change is that multiple lacuna sexually transmitted disease (STD) becomes or large tracts of land infarction kitchen range and atherosclerotic lesion (referring to the neurological, the 4th edition, People's Health Publisher).Clinical treatment can use the cholinergic inhibitor, and blood vessel dilating, cerebral blood flow increasing amount perhaps utilize cerebral protective agent-antioxidant or free radical scavenger can improve ischemia, the caused pathology damage minimizing brain cell necrosis of anoxia and apoptosis, protection cerebral tissue.
The vascular dementia person only shows nearly dysmnesia in early days, and memory far away keeps better relatively; With the increase of the course of disease, memory ability far away is lost gradually, and hypophrenia is gradual and increases the weight of.
And alzheimer disease just shows far and near dysmnesia in early days, hypophrenia presents a kind of (Guo Mingying of progression slowly, Korea S's tinkling of pieces of jade, etc. the comparative study of alzheimer disease and vascular dementia disturbance of intelligence. the journal .2007 of Qinghai Medicine College, 28 (2): 125-127.).
The vascular risk factor is all being played the part of important role in the morbidity of vascular dementia and alzheimer's disease, so there is theory to think that alzheimer's disease and vascular dementia may not be two independent illness.The general character research of alzheimer's disease and vascular dementia is carried out widely in various aspects such as risk factor, pathogenesis, Pathophysiology, iconography changes.
Vascular dementia is the carrying out property decline disease by the acquired Premium Features of cerebral cortex due to apoplexy repeatedly or the long-term chronic cerebral ischemia.
Show in America and Europe's investigation, dementia incidence rate about 1.1% among the old man more than 55 years old, wherein alzheimer's disease accounts for top priority (incidence rate about 7.7 ‰), be about 50%~60% of dull-witted total number of persons, and VD occupies time (incidence rate about 1.5 ‰), account for 10%~20%, and with age, the VD proportion significantly increases (1. Ott A, Breteler MMB, HarskampF, Stijnen T, Hofman A.Incidence and risk of dementia:the Rotterdam study.Am.J.Epidemiol., 1998,147 (6): 574-580.; 2. Di Carlo A, Baldereschi M, Amaducci L, et al.Incidence of dementia, Alzheimer ' s disease, and vascular dementia in Italy.The ILSA Study.J.Am.Geriatr.Soc., 2002; 50:41-48.).
The nearest research of China also shows, the AD incidence rate about 3.5% among the old man of over-65s, VD incidence rate 1.1% (ZhangZX, Zahner GE, Roman GC, et al.Dementia subtypes in China:prevalence in Beijing, Xian, Shanghai, and Chengdu.Arch Neurol.2005; 62 (3): 447-453.).
Owing to also lack the cognitive impairment pattern that is applicable to diagnosis VD at present, discriminating and " mixed type " dull-witted (AD+ cerebrovascular for the diagnosis of AD and VD, be called for short: diagnosis AD+CVD) still has certain challenge (1. plain chrysanthemum of fourth, Li Yunxia. the clinical diagnosis of vascular dementia and treatment. foreign medical science: cerebrovascular disease fascicle .2005,13 (9): 676-680; 2. Erkinjuntti T:Vascular dementia:challenge of clinical diagnosis.Iht Psychogeriatr.1997; 9:51-58.), so someone thinks that vascular dementia may be a dull-witted type the most common among the old people, mainly be because a lot " mixed types " dull-witted (AD+CVD) may be diagnosed as AD (1. Rom á m GC.Vascular dementiamay be the most common form of dementia in the elderly.J Neurol Sci.2002,203-204:7-10; 2. the plain chrysanthemum of fourth. vascular dementia. Chinese gerontology magazine .2003; 23 (4): 200-202.).
The incidence rate of VD is at men and women's no significant difference (Anderson K, Launer LJ, Dewey ME, et al.Genderdifferences in the incidence of AD and vascular dementia:the EURODEM studies.Neurology.1999; 53:1992-1997.), its the most significant risk factor is age [Hebert R., Lindsay J., Verreault R., Rockwood K., Hill G., Dubois MF.Vascular dementia:incidence and risk factors in the Canadianstudy of health and aging.Stroke, 2000; 31 (7): 1487-1493.], according to Epidemiological study, in greater than 60 years old crowd, the sickness rate of 5 years old VD of every increase of age just increases by 1 times.
Two main causes that cause VD are that (ischemic heart disease, be called for short: IHD), and the two all is a commonly encountered diseases in the old people for apoplexy and ischemic heart desease.Only with regard to apoplexy, the present annual whole world increases apoplexy patient 1,000 ten thousand newly, China (the 1. Feigin VL that just has 2,000,000 wherein, Lawes CMM, Bennett DA, et al.Strokeepidemiology:a review of population-based studies of incidence, prevalence, and case-fatality inthe late 20th century.Lancet Neurol., 2003,2 (1): 43-53; 2. Wu Zhao revives, Yao Chonghua, Zhao's winter. the epidemiological study of Chinese population stroke onset rate, mortality rate. and Chinese epidemiology magazine, 2003; 24 (3): 236-239.), sickness rate is high especially in the old people, thereby causes the concurrent VD of a lot of patients.The national dull-witted epidemiology statistics data of China also shows the aging along with population, the change of dietary structure, and the morbidity of VD is and increases progressively trend.
Along with the aging of population, the sickness rate of cardiovascular and cerebrovascular disease raises year by year, and concurrent VD patient also increases gradually.VD is the grievous injury patient health not only, brings long-term misery to the patient, influences patient's quality of life, brings white elephant also for society and family, has caused the common concern of countries in the world, and it is an important topic in the geriatrics field.Generally believe that the age influences by many-side the effect of VD, for example the aging change of metabolism, blood brain barrier and the autonomic function aspect of self the regulating of brain, cell makes cerebrovascular be easy to suffer damage, and encephaloclastic accumulative total effect also is one of reason.
Dementia diagnosis must meet three conditions: 1. dull-witted; 2. cerebrovascular; 3. the two is closely related more than.Dull-witted and apoplexy is maintained close ties with in time, takes place dull-witted usually after the apoplexy in 3 months.Cardinal symptom is: 1. the cerebral tissue pathomorphism changes; 2. hypomnesis.
About the treatment of VD, at present still do not have sure Therapeutic Method and can change the whole course of disease, because downright bad brain cell can not reverse behind the cerebral infarction, mainly be to alleviate stage of attack symptom, prevention infringement etc. again to the treatment of the brain cell of blood supply insufficiency.Normal employing actively improves the method for brain cell oxygen supply, microcirculation improvement, the new thrombosis of prevention and re-infarction etc.Improve cerebral circulation treatment commonly used 9,10-Dihydroergotoxine class, calcium ion antagonist, nicotinic acid class, other medicament for expanding vascellum and medicament for resisting platelet aggregation arranged.Cholinesterase inhibitor is a developed recently dementia treatment medicine comparatively rapidly, example hydrochloric acid donepezil and rivastigmine-hydrogentartrate.Also often should require mental skill clinically and protect medicine such as calcium ion antagonist (nimodipine and western pyrrole spirit); Free radical scavenger (vitamin E, vitamin C and gingko leaf preparation) etc.But from the present Clinical Application effect of said medicine, curative effect is general, and major part all only is anti symptom treatment, can not improve mortality rate.There are weak points such as active component is unclear, mechanism of action not clear, quality is unstable, toxic and side effects is big mostly in preparations such as some Chinese medicine preparation such as Folium Ginkgo, Herba Erigerontis, Radix Et Caulis Acanthopanacis Senticosi at present, are difficult to meet clinical needs.
Therefore, at present countries in the world still do not have effective ways and medicine to controlling this course of disease progress, the drug research of the prevention of VD, treatment and prognosis and exploitation become the research topic paid much attention to various countries (the 1. plain chrysanthemum of fourth. vascular dementia. Chinese gerontology magazine .2003; 23 (4): 200-202; 2. Chen Chunlei, Qiu Zhihui, Su Shixin, Zheng Zhong subtracts, Chen Peifen, Ye Zhiping. the therapeutic advance of vascular dementia. the new .2007 of medical science forum of China, 7 (7): 59-62.).
Therefore; working out a kind of effective Therapeutic Method, to stop potential pathogenic process be very necessary; traditional extract raw material in conjunction with China; therefrom excavate effectively, low toxicity, inexpensive treatment vascular dementia and the medicine of alzheimer disease; the product that is used to prevent, diagnose, detect, protect and treats aspects such as VD particularly medicine has very important significance, and can produce remarkable social benefit and economic benefit.
(4) research overview of antifungal drug
Fungal infection has gradually the trend that increases in recent years, and it comprises superficial part and deep mycosis, and latter's polyphyly body's immunity of falling ill is impaired, often is in a bad way, and threat to life needs whole body use potent antifungal drug treatment.Such medicine can be divided into external and system applies two classes, and external used medicine only is used for mycotic infection of superficial part.
Human fungal infection can involve epidermis, subcutaneous and whole body; Generally can be divided into superficial part and infect (promptly being confined to angleplied laminate, squamous mucosa or cornea) and deep infection (subcutaneous and whole body) two big classes.Their medicine is also different, infects, can be used for deep infection again and there is the part medicine both to can be used for superficial part.Mycotic infection of superficial part comprises dermatomycosis, skin, refers to the infection of (toe) first, hair, as tinea corporis, tinea cruris, tinea manus and pedis, tinea versicolor, tinea unguium, skin mucosa candidiasis and fungal keratitis etc.Superficial mycosis accounts for all dermopathicly 1/4 according to statistics, and particularly foot fungus infection account for department of dermatologry prescription on individual diagnosis patient's 46%, and wherein tinea unguium has just accounted for about 16%; For these infection, mainly adopt local application's treatment, because its infection, medication effect is not often felt quite pleased, and in some situation, also needs oral medication.The local ciclopirox olamine fingernail varnish that uses is coated in the better method that nail surface is the treatment tinea unguium.
Deep fungal infection comprises that subcutaneous tissue and whole body system infect, and comprise candidiasis, cryptococcosis, aspergillosis and mucormycosis etc.In recent years because the increasing of extensive use broad ectrum antibiotic, 17-hydroxy-11-dehydrocorticosterone, immunosuppressant, radiotherapy, chemotherapy, organ transplantation, operative catheter and acquired immune deficiency syndrome (AIDS), make the increase of invasive infections with fungi chance takes place, and cause deep fungal infection increasing, according to incompletely statistics, closely during the last ten years, the sickness rate of deep fungal infection has increased 3~5 times.Infection then needs systemic administration, the drug combination of still needing sometimes for the whole body system.Owing to the mechanism of action difference of medicine, should be noted that their safety and drug interaction problem especially.
In the treatment application facet, deep fungal infection is mainly selected the plain B of both sexes enzyme, itraconazole, ketoconazole, fluconazol, voriconazole, posaconazole, Caspofungin and flucytosine for use, the then mycotic infection of superficial part that are used for of other drug more, but most have more serious toxic and side effects, as amphotericin Toxicity of Kidney arranged.Pathogen also produces drug resistance in various degree gradually in the process of long-term medicinal application, presses for our development of new good effect and the littler antifungal drug of toxic and side effects.

Aspergillus fumigatus is seeded to the SDA inclined-plane, cultivates a week for 35 ℃; Trichophyton, cultivated for two weeks for 28 ℃. after each bacterium activates twice by this method, add an amount of RPMI1640 culture fluid in the SDA inclined-plane, blow and beat bacterium colony with suction pipe, fungal spore is free in the RPMI1640 culture fluid, filtering through four layers of sterile gauze then. culture fluid adds the RPMI1640 culture fluid and adjusts spore concentration to 1 * 10 behind the blood cell counting plate counting 3~5 * 10 3Individual/ml.
2.2. medicinal liquid preparation:
Be subjected to the reagent thing to be made into 6.4gL with DMSO respectively -1Solution ,-20 ℃ of preservations before the experiment, are put 35 ℃ of incubators with the medicinal liquid taking-up and are melted standby.
2.3. drug sensitive plate preparation:
Get aseptic 96 orifice plates, add RPMI1640 100 μ l in No. 1 hole of every row and make blank; 3~No. 12 the hole respectively adds freshly prepared bacterium liquid 120 μ l; No. 2 the hole adds bacterium liquid 160 μ l and l.2~10 grades of 4 times of dilutions in No. 11 hole of test-compound solution 1.6 μ respectively, makes that medicine final concentration in each hole is respectively 64,16,4,1,0.25 and 0.0625,0.0156,0.0039,0.00097,0.00024mgL -1, DMSO content all is lower than 1% in each hole; No. 12 the hole does not contain medicine, makes positive control, and each drug sensitive plate is in 35 ℃ of cultivations.
2.4.MIC 80Value is judged:
Candidiasis, neogenesis cryptococcus and filamentous bacteria are cultivated 24h, 72h and after the week, are surveyed each hole OD value with enzyme micro-plate reader in 630nm respectively at 35 ℃. and with the positive control boring ratio, be MIC with the drug level in the least concentration hole of OD value decline more than 80% 80(drug level when conk 80% is suppressed).
MIC when medicine 80Value surpasses when measuring concentration range, adds up by the following method: MIC 80Value is higher than maximum concentration 64mgL -1The time, count ">64mgL -1"; MIC 80Value is not distinguished for least concentration or when least concentration is following, all counts "≤0.00024mgL -1".
The equal operation repetitive of above-mentioned experiment 2 to 3 times is worked as MIC 80Value just is accepted in the time of accurately repeating or only differ from a concentration, and with higher concentration as MIC 80Value is worked as MIC 80Value differs two concentration when above, then needs experiment again, till meeting the requirements.The data show compd B is for Candida albicans in the table 13, and the effect of neogenesis cryptococcus is better than griseofulvin.
