Abstract
The present invention relates to a method for extracting oligosaccharide from Chinese medicinal plants, which belongs to the technical field of traditional Chinese medicine. The present invention relates to a preparation method of morinda root oligosaccharide, particularly to a preparation method of morinda root total oligosaccharide. The present invention is characterized in that coarse powder of morinda root medicinal materials is refluxed and extracted by 95% of alcohol first, and after refluxed and extracted by water, residues are deposited by 80% of ethanol; supernatant liquid is concentrated in vacuum to liquid extract, and impurities of the liquid extract are removed orderly by weak acid, weak alkali and weak acidic resin; finally, the supernatant liquid whose impurities are removed is processed by chromatography, decoloring, vacuum concentration and freeze drying, and thus, the white crystal of morinda root total oligosaccharide is obtained. The morinda root total oligosaccharide of the preparation method has the advantages of high yield, simple manufacturing process, low cost and convenient industrial production.
Description
Affiliated technical field:
The present invention relates to technical field of traditional Chinese medicines, relate to from Chinese medicinal materials the method for extracting oligosaccharides, a kind of preparation method of morinda root oligosacchride specifically, the preparation method of the total oligosaccharides of particularly a kind of Root of Medicinal Indian mulberry.
Background technology:
As everyone knows, Root of Medicinal Indian mulberry has higher pharmaceutical use, is one of China's work bright " four Da Nan medicines ".Morinda root oligosacchride (Bajitian oligosaccharide) is to extract, make with extra care the mixture that obtains from the root of Root of Medicinal Indian mulberry.Modern Chinese herbal medicine is learned and be studies show that, morinda root oligosacchride has the spermatogenesis effect of promotion and antidepressant effect, thereby makes having a sudden rise in social status of Root of Medicinal Indian mulberry, and some businessmans do not stint huge fund and this developed research in the industry, but still are in the starting stage at present.About the morinda root oligosacchride extracting method, Chinese Military Medical Science Institute utilizes sephadex column to separate and has obtained the 4-7 oligosaccharides, but content is lower, and sephadex column is more expensive; In addition, this method is had to the monomer of a Root of Medicinal Indian mulberry 4-7 monose, has lost the monomer oligosaccharide that other series has very high pharmaceutical use equally; Especially this method only is in experimental stage, and real industrialization is still difficult.
Summary of the invention:
Technical problem to be solved by this invention is to improve the extraction yield of morinda root oligosacchride, simplifies extraction process simultaneously, reduces production costs, and is beneficial to suitability for industrialized production.
The technical solution that the present invention solves the problems of the technologies described above is:
The preparation method of the total oligosaccharides of a kind of Root of Medicinal Indian mulberry is a raw material with the Root of Medicinal Indian mulberry root, and technological process is extraction, impurity elimination and refining three steps, and concrete preparation method is as described below:
1) extract: the Root of Medicinal Indian mulberry medicinal material coarse powder is used alcohol reflux earlier, and the residue that discards oil-soluble impurities is the water refluxing extraction again, and the water extract of gained adds ethanol sedimentation, gets supernatant liquid filtering then and is concentrated into flowing soaking paste;
2) resin removal of impurities: the fluid extract of gained is removed alkaline impurities with weakly acidic cation-exchange resin earlier, removes acidic impurities with weak base anion-exchange resin again, uses the removal of impurities of slightly acidic exchange resin at last, must remove OH
-The ionic neutral oligosaccharides aqueous solution;
3) decolorizing and refining: the neutral oligosaccharides aqueous solution that will obtain through step 2 is through decolorizing with activated carbon, vacuum concentration, and lyophilize promptly obtains the white crystals of the total oligosaccharides of Root of Medicinal Indian mulberry.
Because the water liquid-extracting amount of gained is big behind the extracting in water, in order to reduce next step treatment capacity, first important additional technical feature of the present invention is water extract elder generation evaporation concentration to 80% is added ethanol sedimentation again.
Removal of impurities process of the present invention is very crucial, is directly connected to the quality and the yield of finished product, and therefore the working medium of used weak acid and weak base will be controlled its ratio and select the optimum handling order.Second important additional technical feature of the present invention is that resin removal of impurities process is: remove alkaline impurities with the weakly acidic cation-exchange resin of 3 times of fluid extracts earlier, remove acidic impurities with the weak base anion-exchange resin of 3 times of fluid extracts again, use 1/2 times of slightly acidic OH at last
-The ion exchange resin removal of impurities.
The 3rd additional technical feature of the present invention is to add 30-40 80% ethanol sedimentation doubly after the Root of Medicinal Indian mulberry aqueous extract evaporation concentration, to improve the yield of fluid extract.
Therefore activated carbon decolorizing is important step of purified, is related to the quality of finished product, and the 4th the additional technical feature of the present invention activated carbon consumption that is to decolour is 10 times of fluid extract.
The total oligose preparing process of Root of Medicinal Indian mulberry of the present invention has following outstanding advantage than prior art:
1) higher yield is arranged, what obtain is the total oligosaccharides of Root of Medicinal Indian mulberry, detects it through flight time mass spectrum and consists of the total oligosaccharides of series that 1-22 left and right sides monose is formed, and yield is about 5% of crude drug; 2) extraction, removal of impurities, process for purification are simple, and the technological process time is short; 3) material is chosen conveniently, can use the different weak acid and weak base resins of producing the different model of family's production to remove impurity; 4) low cost, used industrial media ethanol, weak acid and weak base resin are all more cheap.5) simple to operate, security is higher, and agents useful for same is all fool proof.
