PURIFICATION METHOD OF VITEXIN EXTRACTED FROM SEED COATS OF MUNGBEAN

摘要

More specifically the present invention relates to a kind of the pure of mung bean derivation using Vittek god for placing mung bean byproduct, the method of low cost and advantageously crop (mung bean), after the treatment by using a commercial-product of pure water, in order to utilize low cost, rapidly put Vittek (mass percent) separation and purification whitening product, one functional food, so much so that the raw material for a technology of industrial application as sedative enabled. It is related to;According to the present invention, derived from using the mung bean of Vittek god pure, inexpensive method mung bean mung bean of lying is placed there is the mung bean byproduct of 80% alcohol to extract product or 80% methanol; Defatting step with carrene; Solvent fractionation step with ethyl acetate; For the step of concentrating at high concentration class; Step represents a period acquisition one concentrate ratio teksin precipitating; Unless being characterized in that except teksin using alcohol or methanol, it includes: step separation impurity.
