| 摘 要： | 用w(C2H5OH)=70%的工业乙醇从脱脂大豆饼中提取大豆异黄酮,并依次用乙酸乙酯、正丁醇萃取,乙酸乙酯萃取部分经硅胶柱和SephadexLH-20柱层析,用V(CHCl3)∶V(CH3OH)=(12～4)∶1梯度洗脱。分离得到4种化合物,通过理化常数和光谱分析鉴定其化学结构,分别为大豆甙元(daidzein)、染料木素(genistein)、大豆甙(daidzin)、染料木甙(genistin)。

| Abstract: | Defatted soybean flour was extracted by w (C_2H_5OH)=70% ethanol,and the extract was extracted by ethyl acetate and n -butanol in turn. Isolation and purification of the ethyl acetate section were carried out on silica gel column chromatography and Sephadex LH-20.Four compounds were isolated,identified and elucidated by physicochemical properties and spectral analysis.They were daidzein,genistein,daidzin and genistin. |
