【摘要】 试验采用80％的乙醇溶液萃取脱脂豆粕,将浸取液蒸发浓缩后,用正己烷萃取脂溶性物质,用盐酸除去蛋白,经分离后用大孔树脂进行纯化,最后用丙酮萃取提纯,大豆异黄酮纯度可达到70.56％,其中大豆甙元占44.66％,染料木黄酮糖甙为55.34％。更多还原

【Abstract】 In the experiment,80% ethanol solvent is used to extract degreased soybean meal, after evaporating and concentrating the extraction solution, we use the n-hexane to extract the liposoluble material, hydrochloric acid to remove protein, after separation, use the macroporous resin and acetone to purify, then can get the soybean isoflavone with 70.56 % content, thereinto, the daidzin 44.66 % , the genistin 55.34 % .更多还原
