Description
Technical field
The present invention relates to a kind of ganoderma lucidum fruitbody refined polysaccharide with notable adjunct antineoplastic activity and preparation method thereof
And application, belong to extraction and separation technology and medicine food application and development field.
Background technology
Effect of the edible mushroom to human health is increasingly by the extensive attention of international community.Edible fungi polysaccharide is as edible
One of main active of bacterium, as the study hotspot of World Health industry.Numerous studies document shows that edible mushroom is more
Sugar has immunological regulation, antitumor, antiviral, anti-aging, and a variety of biologies such as anti-oxidant, reducing blood lipid, hypotensive, hypoglycemic are lived
Property.At present, the state such as the Asian countries headed by China and America and Europe is to a variety of foods such as ganoderma lucidum, mushroom, Agricus blazei, grifola frondosus
More systematic research is carried out with granulose, wherein ganoderma lucidum and GL-B turns into research with its unique healthcare function
Focus.
Modern pharmacology and clinical practice confirm, GL-B be ganoderma lucidum strengthen the body resistance to consolidate the constitution, strengthening by means of tonics, the master to promote longevity
Want effective substance.GL-B has stimulation of host non-specific resistance, immune idiosyncrasy and suppresses transplantation tumor life
The characteristics such as activity are managed, immunity of organisms and hypoxia-bearing capability can be improved, there is significant medicines and health protection application value, social benefit
And economic benefit.
Ganoderma lucidum fruitbody is made up of main components such as chitin, cellulose, hemicellulose, lignin, close structure and work
Property polysaccharide be attached on the inside of cell membrane, and it is most of molecular complex is directly formed with protein, extraction purification difficulty is larger.Mesh
Preceding Extraction method of ganoderan mainly has:Hot water extraction method, extraction, ultrasound assisted extraction method, microwave―assisted extraction,
Enzyme process assisted extraction.
Although extraction recovery rate is higher, equipment is corrosion-resistant to require high, and cost is expensive, and the three-dimensional of active polysaccharide is stood
Body structure easily changes, and finished product color is deep, impurity is more, is unfavorable for being received by consumer, but also fixed-end forces be present
Problem, operating cost accordingly improve.It is bright that although ultrasonic extraction and microwave loss mechanisms have, recovery rate is high, extraction time is short etc.
Aobvious advantage, but single treatment amount is low, and equipment pays for cost height first.Also, the thermal transition efficiency of ultrasonic extraction is low, does not meet energy-conservation
It is required that noise is big, it is unfavorable for health.Microwave Extraction is substantially also in laboratory stage, because the penetration depth of microwave has
Limit, is only capable of penetrating 4.5cm in pure water, is not suitable for big tank extraction, and the so-called Microwave Extraction Equipment introduced at present in production is basic
Only it is to replace steam or conduction oil to provide thermal source with microwave, is not microwave extraction technology truly, still falls within heat
The category of water extraction, it is impossible to produce from cell interior and destroy cell membrane, promote the effect of active ingredient release.So to current
Untill ultrasound assisted extraction and microwave radiation exaraction not yet realize real industrial applications.
Enzymatic Extraction belongs to efficient cryogenic extractive technique, and the yield of Enzymatic Extraction is very high, but Enzymatic Extraction is equally with aobvious
The defects of work, including:(1) dissolution rate of impurity and the dissolution rate of active principle are directly proportional, have been even more than active ingredient increase
Multiple, introduce substantial amounts of impurity, be unfavorable for purifying and prepare high-purity product, therefore Enzymatic Extraction technology is less is actually applied
In the kind for needing later-period purification to separate.(2) Enzymatic Extraction needs medicinal material is broken as far as possible, to allow enzyme to greatest extent
Effective contact is formed with substrate, so as to improve product yield, but meets that the medicinal material broken enough of enzyme process requirement is real to production
Border brings many troubles, for example blocks liquid outlet and filter medium, production is not normally carried out, such as the water content of the dregs of a decoction
It is high compared with the medicine materical crude slice class dregs of a decoction, target component because extract solution is adsorbed by the dregs of a decoction and caused loss is also big, fixed-end forces cost is also entered
One step increase etc..(3) common enzyme will play preferable hydrolysis result on the market at present, be required for adjusting pH value to certain enzyme
Near optimum PH, such as the optimum PH of pectase, cellulase, pepsin is below 4, equally can under heating environment
Cause some unknown impurity that chemical property occur to change, because impurity is unknown, the reaction product of it and soda acid may also
It is unknown, effective monitoring can not be formed in produce reality, therefore certain Clinical practice risk may be brought.(4) one is entered
Step ground, applicant is in production practices, it was also found that the taste and flavor of enzymatic extract is significantly worse than direct decocting, it may be possible to wind
There occurs the change of essence in Acid-Base System for taste composition, such as amino acid, nucleotides, volatile oil.(5) for cost viewpoint,
The enzyme that can apply in production is the direct enzyme that tentatively simple purification is just launched immediately after microbial fermentation, these
Enzyme is actually the dominant complex enzyme of a certain enzyme, rather than the price that biochemistry uses is high, the single specificity of high-purity
Enzyme, this complex enzyme is used in production, the same risk being decomposed with desired polysaccharide.

GL-B is the glucan with helical form spatial configuration (three-dimensional structure) being made up of three strands of monose chains, and it is vertical
Body configuration is similar to RNA, DNA, is a kind of macromolecular compound.Have document report at present, purify and obtain from ganoderma lucidum fruitbody
The unimodal polysaccharide obtained, after chemistry or biodegradation, the presence of amino acid is detected, inferring in its structural framing to gather
Conjunction has polypeptide, protein.After the stereochemical structure of GL-B is opened and is changed into planar structure or linear structure, or ganoderma lucidum
After proteoglycans that may be present, the configuration in peptide glycan activated centre change in polysaccharide, many pharmacology of GL-B are lived
Property also weaken or disappear therewith, so, applicant design in the extracting and developing of GL-B, purifying, drying and other steps
In, using gentle physical method, to protect its three-D space structure and activated centre configuration to greatest extent, acquisition have compared with
The finished product of high pharmacological activity.
Applicant detects discovery in process exploitation, and when ganoderma lucidum fruitbody is extracted using hot water, the polysaccharide in extract solution is dense
Degree is far below protein concentration (polysaccharide 0.67mg/mL, protein 1.44mg/mL), or even the polysaccharide-protein ratio of indivedual raw materials reaches
Into 1:2.5.The content of Thick many candies (survey by anthrone-sulphuric acid method in the GL-B that traditional water extract-alcohol precipitation drying process is obtained
It is fixed) it is only 28~35%, and protein content is up to 38%~51%.By obtained GL-B with being filtered after boiling water back dissolving, filter
Slag drying is weighed, and finds not redissolving the color of thing close to ater, weight up to throws the 7~13% of GL-B, through physics and chemistry
Differentiate, it is found that this does not redissolve the mixture that thing belongs to protein, macromolecular pigment and cellulose.Filtrate is concentrated to alcohol precipitation again to do
After dry, continue to determine the content of Thick many candies, it is found that content is increased to 38~47% sections, protein content is reduced to 32nd~44% area
Between, but still it is not reaching to the purity required by active component new drug development.As can be seen here, in production practices, want to obtain
Quality preferably, GL-B of high-purity, high activity, it is necessary to pointedly carry out suspended things removing, albumen removing and pigment
Removing is handled.
The impurity source of Thick many candies product is mainly impurity protein, pigment, cellulose, inhereditary material and small-molecule substance etc.
Non-active ingredient, the exterior quality of GL-B product is greatly have impact on, reduce the content of active polysaccharide so as to reduce
Clinical drug effect.At present, being related to the discoloration method of GL-B mainly has organic reagent preextraction, charcoal absorption, dioxygen water oxygen
The methods of change, chlorite oxidation are decolourized.It is applicant's understanding that there is the defects of certain in these methods:Oxidative decoloration method can be broken
The three-dimensional active structure of polysaccharide is broken, makes its many-sided reduction evident in efficacy;Charcoal absorption belongs to traditional decolouring technology, is
A kind of indifference, the technology without adsorptive selectivity, while the removal of impurity is gone, the loss of polysaccharide is also very big;In ganoderma lucidum fruitbody
Pigment be water miscible macromolecular pigment, organic reagent preextraction decolorizing effect is little.
At present, in ganoderma lucidum crude polysaccharide protein removal methods, use Savag methods, this method mostly in laboratory stage
Using a large amount of organic solvents and cumbersome, treating capacity is low, and manpower consume is big, is not belonging to scale industrialization technology.Producing
Stage mainly uses charcoal absorption, and de- albumen while decolourizing, actual removal efficiency is low, and polysaccharide loss is big.Also have one in addition
Staticly settle, high speed centrifugation the methods of, belong to time-consuming method longer, single treatment amount is extremely low, have a strong impact on production effect
Rate.
Therefore, applicant thinks, at present, is essentially consisted in for the extraction purification difficult point of GL-B in efficient removal
While the impurity such as albumen, pigment, retain polysaccharide as much as possible, improve polysaccharide yield, and keep the activity of polysaccharide.
On this basis, applicant's analysis finds, extraction of the prior art for GL-B, main method be divided into
Under several classes:
1st, as described in patent application CN201210557813, using the extraction of ultrasonic wave associated proteins enzyme, 10KD is used again
The scheme of permeate, concentration and alcohol precipitation is collected in ultrafiltration, is disadvantageous in that and is used zymyhydrolyzed protein, and it is small to form hydrolysate
Molecular polypeptide and amino acid, it is still present in permeate in 10KD ultrafiltration technologies, is not sloughed really.This kind of method is present
Do not decolourized targetedly and/or Deproteinated problem, prepared GL-B purity is limited and/or finished appearance product
Matter is general.
2nd, as described in patent application CN201410778126, cold analysis removal of impurities is carried using enzyme, then alcohol precipitation back dissolving adds tannic acid
Secondary precipitation is cleaned, supernatant activated carbon decolorizing, and vacuum drying scheme is concentrated after 30KD ultra filtering clarifyings.Through looking into, tannic acid molecule
Measure as 1701, and belong to two molten thing of alcohol water, described according to its technique, the tannic acid impurity being newly introduced into can not remove in subsequent technique
Totally, finished product is polluted.Patent CN201510764260 uses sodium chlorite-glacial acetic acid system oxidative decoloration, then ultrasonic extraction alcohol
Heavy scheme, active polysaccharide structure is destroyed big.This kind of method introduces new impurity or condition when removal of impurities be present and acutely caused very much
The problem of active polysaccharide is destructurized.
3rd, as described in patent application CN200510014592, using pre-treatment, micro-filtration, freezing separation, UF membrane, film
The technical matters concentrate, be concentrated under reduced pressure, being dried under reduced pressure, this kind of technique imurity-removal needs will all unconcentrated extract solution freezings
To 0 degree once, cost is very big, the difficulty of equipment, production efficiency it is low, can be sayed without any volume production advantage.In another example patent
CN201310742219 combines ring current method by high speed centrifugation and removes isolating protein, using 6000~14000r/min centrifugal clarifications;
If belonging to commercial processes, As-Is analysis is equipped according to current industry, the centrifuge of this rotating speed can be reached in production practices
Only tube centrifuge, and the single treatment capacity of tube centrifuge maximum at present is less than 25L, if needed per 25L extract solutions
10-120min is centrifuged, treating capacity is less than 150L, from production efficiency and energy cost, no volume production advantage per hour.As specially
Profit application CN201510822880 adds 15~20 times of amount distilled water to extract 2 times using raw material, centrifuging and taking supernatant, adds supernatant
Liquid accumulates the technical matters of 85~95% ethanol progress subsequent treatment of 3~5 times of amounts;The ethanol of the technique is extrapolated accordingly most
Low usage amount is that reagent consumption expense is much larger than output benefit, without any volume production advantage per kg medicinal material 90L.This kind of method is all deposited
It is too high in cost, the problem of no industrialization prospect.
4th, as described in patent CN201510541581 applications, after being redissolved again using water extract-alcohol precipitation, received with hollow-fibre membrane
Collect the trapped fluid between 50,000~80,000, finally with activated carbon decolorizing, the technical matters for filtering and being spray-dried;This technical matters mesh
Mark polysaccharide molecular weight cut coverage is too narrow, and inevitable yield is very low, and carries out adsorption bleaching from activated carbon, and polysaccharide loss is big.
In another example described in patent application CN201410628578, using cellulase and compound protease, and simultaneously
United microwave method extracts the technical scheme of GL-B.Inferred according to the general understanding of industry practitioner, Enzymatic Extraction
Impurity how much be directly proportional to the increased multiple of yield, yield is higher, and impurity is higher, and the patent configuration activated carbon inhale
Attached impurity removal process, belong to non-selective adsorption impurity removing technology, specificity removal of impurities effect is not too much high, and general labourer is removed using activated carbon
The shortcomings that skill, also existence time are long, loss is big, activated carbon is difficult to filtering.
5th, as described in patent application CN201110161167, using multiplex-enzyme extraction, ultrafiltration retention 100,000~1,000,000
Compound molecular weight, the technical matters of weak-base anion-exchange resin chromatogram purification;Its polysaccharide molecular weight section blocked is not
The polysaccharide enrichment section of raw material, therefore yield is not high, while also there is the general defect of Enzymatic Extraction.
As described in patent application CN201110184693, using first water extraction, then concentration of alcohol is adjusted to 20~30%
Precipitation, obtains light Ganoderma lucidum polysaccharide of high molecular weight, according to the general sex experience of industry practitioner, can 20~30% second
The polysaccharide molecular weight being precipitated out in alcoholic solution is at least more than million grades, and the polysaccharide section is not the polysaccharide enrichment section of raw material, therefore
Yield is not high.
The theoretical yield in GL-B in above-mentioned two patent application is all relatively low.
In summary, extract by research of the applicant for GL-B structure, molecular weight etc. and in the prior art
The analysis of method, it has been found that in extracting method, extraction of the hot water extraction method to polysaccharide is gentleer, survivable polysaccharide
Structure, still, there is the problem of protein content is high in polysaccharide extraction liquid in such mode, for this problem, prior art
Generally use enzymolysis overcomes, however, applicant passes through theory analysis and practice, it is believed that:Enzyme-extracting solution by protein digestion into
Amino acid, polypeptide, but prove that the active component of GL-B is holosaccharide without definite evidence at present, educational circles's analysis is purified into
Unimodal polysaccharide contains certain protein, i.e. active component is likely to be by the polysaccharide of polypeptide, protein structureization modification, enzymolysis
During albumen, the fracture of peptide bond is random, can both cut off impurity protein, can also cut off the activity of activated protein glycan at any time
Center, so, enzymolysis step takes chemical valence link fracture removing, has the steric configuration that may change active macromolecules thing,
So as to influence the risk that activated centre plays function.
Thus, applicant carries out de- protein decolouring after hot water extraction using resin, and by the research hair to resin
Existing, using single strong polymeric adsorbent, such as during Anion-adsorption resin, the loss for polysaccharide is larger, it is understood that there may be peptide gathers
Sugar, the loss risk of proteoglycans constituents, are combined, Cai Nengda using the moderate polyamide of absorption affinity with resin anion (R.A.)
To that can remove pure impurity protein and glycoprotein as far as possible, and can, which is tried one's best, retains the purpose of proteoglycans and peptide glycan.
Applicant further repeatedly practises discovery, and it is 1~2 meter to select polyamide resin column filling height, resin anion (R.A.)
When 20~40cm of post bed height series connection resin carries out de- protein decolouring, it is larger that egg white by proportion in preferably removing molecule can be reached
Pure impurity protein and glycoprotein, while retain the effect of the less proteoglycans of egg white by proportion and peptide glycan again, decolourize simultaneously
Effect is also preferable.
Applicant also found that GL-B is present in ganoderma lucidum fruitbody, is by multiple differences in GL-B extraction
The mixture of the polysaccharide molecule composition of molecular size range, using HPGPC methods to GL-B made from traditional aqueous extraction-alcohol precipitation technology
Molecular weight distribution investigation has been carried out, it is found that GL-B is substantially different from lucid ganoderma spore powder polysaccharide and lucidum mycelium polysaccharide, its
The molecular weight of polysaccharide is smaller;According to appearance time, Wo Menchu corresponding to the different molecular weight dextran reference substance of narrow ditribution
Step find the overwhelming majority GL-B molecular weight appearance time be respectively positioned on dextran D5000 and D50000 appearance time it
Between, i.e., molecular weight is between 5.22~48.6KD.
Based on this, when developing preparation method, particularly clarification process, purifying process, concentration process steps when, to used
The aperture of material carries out planned selection all referring to above-mentioned molecular weight data, realizes most preferred effect.
In the third aspect of the present invention, there is provided what a kind of above-mentioned preparation method was prepared there is notable adjunct antineoplastic to live
The ganoderma lucidum fruitbody refined polysaccharide of property, the polysaccharide and the polysaccharide properties that first aspect present invention provides are same or similar.
