- 摘要:
- 以大豆胚轴为原料 ,通过正交设计确立制备含染料木黄酮的糖配体酸水解条件,水解酸液的浓度为 2. 5 mol/L 、水解温度为 90℃,水解时间为 3h 。根据糖配体的溶解度与极性经 AB - 8 大孔树脂柱乙醇溶剂分步淋洗(水 →30 %乙醇 →80%乙醇)分离及以氯仿 ∶甲醇 ∶20%冰乙酸, 体积比为 7∶3 ∶1 为展开系薄层小量制备出纯度为 48. 6%大豆异黄酮糖配体染料木黄酮 。
- Abstract:
- By orthogonal experimental methodology , the optimum parameters of acid hydrolysis for agly-con including Genistein were established, as follows:concentration of ethanol of acid, 2. 5 mol /L ;temper-ature, 90 ℃;and time 3h. According to solubility and polarity the Genistein of 48. 6%purity was preparedwith macro - pore resin AB - 8 desorping of terraced concentration(water →30%ethanol →80 %ethanol)and thin layed which the mixture of chloroform :methanol ∶20%acetic acid(7∶3∶1)was mobile phase.
