Abstract
The present invention is the method of extracting effective components in kudzu vine root. The present invention features that during the separation of effective components in kudzu vine root, S-8 resin is used to adsorb the effective components of the concentrated extractive and mounted in chromatographic column for elution with ethanol or methanol solution of 30-50 %, 50-80 % and 80-100 % concentration separately, and the three kinds of eluted liquid are collected separately and concentrated, crystallized and dried separately. The said process can extract and separate the three kinds of effective components, including puerarin, daidzin and daidzein simultaneously and this can raise the utilization value and make full use of the Chinese medicine resource.
Description
Technical field
The present invention relates to a kind of from the root of kudzu vine method of extracting effective components.
Background technology
The root of kudzu vine is a kind of traditional Chinese medicine, contain many kinds of effective constituents, wherein based on puerarin, daidzin, daidzein, puerarin has special effect at aspects such as treatment cardiovascular disorder, stenocardia, daidzin and daidzein are treating and are preventing aspect the symptoms such as female diseases such as mammary cancer, osteoporosis, hot flush special role is arranged, in present medical research, daidzin, daidzein and puerarin have all obtained attention.In the method for existing extraction kudzu vine root, water extract-alcohol precipitation method of purification, polyamide column chromatography method of purification, water extraction method, kudzuvine root starch processing waste water resin isolation method etc. are arranged.These methods all are only to extract a kind of effective constituent of puerarin, and the while extraction separation does not go out daidzin and these two kinds of effective constituents of daidzein, thereby make daidzin and daidzein in the root of kudzu vine not obtain utilizing, influenced the economic benefit of extracting the root of kudzu vine, reduce the utility value of the root of kudzu vine self, caused the waste of Chinese material medicine resource.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes above-mentioned prior art, a kind of method that can extract plurality of active ingredients simultaneously from the root of kudzu vine is provided, effective constituent in the root of kudzu vine is fully extracted, improved the utility value of the root of kudzu vine self, make full use of Chinese material medicine resource.
Technical scheme of the present invention is such: a kind of method of extracting plurality of active ingredients in the root of kudzu vine, comprise extracts active ingredients, separation and aftertreatment, it is characterized in that in the sepn process of effective constituent, its polymeric adsorbent that adopts is the S-8 resin, with the effective constituent in the S-8 resin absorption extract concentrated solution, this resin is packed in the chromatography column, be that the ethanol of 30-50%, 50-80%, 80-100% or methanol-eluted fractions are contained in the resin in the chromatography column with concentration successively, collect the solution that above-mentioned wash-out comes out respectively; The aftertreatment of effective constituent be to three kinds of solution that above-mentioned wash-out obtains concentrate respectively, crystallization, drying treatment.Described S-8 resin is the commercial goods, it can adsorb three kinds of effective constituents, be puerarin, daidzin and daidzein, with concentration is to contain the puerarin composition in the ethanol of 30-50% or the solution that methanol-eluted fractions is come out, with concentration is to contain the daidzin composition in the ethanol of 50-80% or the solution that methanol-eluted fractions is come out, is to contain the daidzein composition in the ethanol of 80-100% or the solution that methanol-eluted fractions is come out with concentration.This method of three kinds of effective constituents of extraction separation simultaneously, it is fully extracted the effective constituent in the root of kudzu vine, has improved the utility value of the root of kudzu vine self, makes full use of Chinese material medicine resource.
