Abstract

The invention discloses a method for preparing glycitein by taking bean germ as a raw material. The method comprises the following steps: conducting extracting on 80-100-mesh bean germ powder in 55-65% ethanol for 45-60 minutes to obtain an extracting solution, wherein 500-600ml of an ethanol solution is added into every 100g of the bean germ powder, and evaporating the extracting solution to dryness to obtain dry residues; adding n-hexane into the dry residues for extraction, and then discarding an n-hexane supernate to obtain residues; and adding ethyl acetate into the residues for extraction, conducting centrifugation to obtain a supernate, and evaporating the supernate to dryness to obtain the glycitein. When the bean germ powder is subjected to extraction by a specific process, single-component isoflavone-glycitein can be extracted, and a glycitein pure product is obtained after n-hexane degreasing and impurity removal by ethyl acetate. The method is simple, rapid, low in cost andsuitable for industrial production.
