【摘要】 对黄芪皂甙的几种提取分离方法 :水提法、醇提法、萃取法精制、树脂吸附法精制和超临界 CO2 法进行了试验研究。结果表明 ,醇提法优于水提法 ,树脂吸附法明显优于正丁醇萃取法 ,用超临界 CO2 法提取时以甲醇和体积分数为 95的乙醇作为夹带剂提取效果较好更多还原

【Abstract】 Various methods of extracting and isolating astragaloside like water extracting, ethanol extracting, extraction refine, resin absorbing have been carried out. As a result, ethanol extracting is better than water extracting, resin absorbing method is better than extraction refine by n butyl alcohol, and when the supercritical CO 2 method were used, methanol and 95 % ethanol as entrainment agent can get a better result.更多还原
