Description
Technical field
The present invention relates to a kind of method, belong to the anemaran technology of preparing by wind-weed medicine materical crude slice extraction anemaran.
Background technology
Polysaccharide is a class biomacromolecule material, has begun extensive studies from 20th century, studies have shown that polysaccharide has a series of pharmacologically active, as: enhance immunity power, hypoglycemic, anti-inflammatory, antitumor etc.Compare with the medicine that existing market is used, have effective, nontoxic advantage.Bibliographical information has proved that anemaran is that a class has the polysaccharide that higher pharmacology is worth, and especially the effect aspect hypoglycemic is more outstanding.Therefore extract the focus that anemaran becomes anemaran research preferably.
The wind-weed (Rhizome Anemarrnema) is the dry rhizome of the liliaceous plant wind-weed (Anemarrhenaashphodeloides Bge), and the property bitter taste is cold, has heat-clearing and fire-purging, and the effect of promoting the production of body fluid and moisturizing is a class heat-clearing and fire-purging drug commonly used.
Use for the research of the wind-weed at present, mainly concentrate on the various small molecules compositions that ethanol-extracted obtains, wherein main component contains steroid saponin, flavonoid, lignin and sterols, pharmacological actions such as that these compositions have is antitumor, reducing blood-fat, anti-senile dementia and anti-inflammatory, in the application in modern times also relatively extensively.
Existing method by wind-weed extraction anemaran only limits to the water extraction of the wind-weed, as usefulness distilled water refluxing extraction Common Anemarrhena Rhizome 1h such as Zhou Yonggang, extracting solution merges the concentrated extracting solution that promptly obtains anemaran, and the content of anemaran in the extracting solution carried out measuring (Zhou Yonggang, Bian Yanfang, Chen Wansheng. the assay of wind-weed total polysaccharides [J]. pharmacy practice magazine, 1999,17 (5): 306-307.); Guan Honghui etc. reflux Common Anemarrhena Rhizome 3 times 90 ℃ of water-baths, each 40min, merging filtrate, concentrate, four times of ethanol sedimentations have obtained general extractive (Guan Honghui, the Guo Qiuping of anemaran, Gao Ying, Deng. Mangiferin and content Determination of Polysaccharide [J] in the wind-weed in the different places of production. the time precious traditional Chinese medical science traditional Chinese medicines, 2009,20 (1): 182-184.).
The weak point of this method is that the residue after water is carried is considered as refuse and abandons, and causes the anemaran effective constituent in the residue to waste.
The present invention has been primarily aimed at the difference of the soda acid character of anemaran, adopts two kinds of solvents that the polysaccharide in the wind-weed medicine materical crude slice is extracted, and has prepared two kinds of anemarans, has enriched the kind of polysaccharide, has improved content.
Summary of the invention
The object of the invention provides a kind of method by wind-weed medicine materical crude slice extraction anemaran, and this procedure is simple, and the anemaran composition of extraction is many, widens the anemaran pharmacologically active.
The present invention is realized that by the following technical programs a kind of method by wind-weed medicine materical crude slice extraction anemaran is characterized in that, may further comprise the steps:
(1) with wind-weed medicine materical crude slice after 60~65 ℃ of dryings of temperature, pulverized 100 mesh sieves, the accurate title, decide, it is added mass concentration is that 60~80% aqueous ethanolic solutions are at 90 ℃ of refluxing extraction 1~3h of temperature, the reject extracting solution, and carry out refluxing extraction 3 times by the 1st refluxing extraction operational condition, then filtered and recycled Common Anemarrhena Rhizome residue;
(2) with step (1) Common Anemarrhena Rhizome residue in temperature 60-65 ℃ drying, mass ratio by exsiccant Common Anemarrhena Rhizome residue and deionized water is 1: (10~30), the Common Anemarrhena Rhizome residue is added in the deionized water, at 60~100 ℃ of refluxing extraction 1~3h of temperature, reclaim extracting solution, and carry out refluxing extraction 3 times by the 1st refluxing extraction operational condition, recycle-water is carried wind-weed medicine materical crude slice residue, united extraction liquid.The extracting solution that merges concentrates through reduction vaporization, 3 times the ethanol that in concentrated solution, adds volume, precipitate 23-25h down at temperature 3-4 ℃ then, reclaim supernatant liquor, throw out washs with dehydrated alcohol, ether, wash do not have color to washings till, suction filtration, it is 40%~50% neutral polysaccharide N that the filter cake lyophilize obtains mass content
1Be main wind-weed medicinal extract;
(3) supernatant that step (2) is reclaimed concentrates through reduction vaporization, 4 times the ethanol that in concentrated solution, adds volume, precipitate 23-25h down at temperature 3-4 ℃ then, remove supernatant liquor, throw out washs with dehydrated alcohol, ether, wash do not have color to washings till, suction filtration, it is 60%~70% neutral polysaccharide N that the filter cake lyophilize obtains mass content
2Be main wind-weed medicinal extract;
(4) water that step (2) is reclaimed is carried the Common Anemarrhena Rhizome residue after 60~65 ℃ of dryings of temperature, the ratio of carrying Common Anemarrhena Rhizome residue quality gram number and sodium hydroxide solution volume milliliter number by exsiccant water is 1: (10-30), water is carried the Common Anemarrhena Rhizome residue to add in 0.1~0.3mol/L sodium hydroxide solution, at 60~100 ℃ of refluxing extraction 1~3h of temperature, reclaim extracting solution, and carry out refluxing extraction 3 times, united extraction liquid by the 1st refluxing extraction operational condition.In united extraction liquid, drip 0.1~0.3mol/L hydrochloric acid to the pH of united extraction liquid be 6~8, concentrate through reduction vaporization, 3 times the ethanol that in concentrated solution, adds volume, precipitate 23-25h down at temperature 3-4 ℃ then, reclaim supernatant liquor, throw out is with dehydrated alcohol, ether washing, wash do not have color to washings till, it is 30%~40% acidic polysaccharose A that suction filtration, filter cake lyophilize obtain mass content
1Be main wind-weed medicinal extract;
(5) supernatant liquor that step (4) is reclaimed concentrates through reduction vaporization, 4 times the ethanol that in concentrated solution, adds volume, precipitate 23-25h down at temperature 3-4 ℃ then, remove supernatant liquor, throw out washs with dehydrated alcohol, ether, wash do not have color to washings till, after filtration, it is 40%~50% acidic polysaccharose A that the filter cake lyophilize obtains mass content
