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
【英文摘要】
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.
