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 Several extraction and separation methods for Astragalus membranaceus: water extraction, alcohol extraction, extraction refining, resin adsorption refining and supercritical CO2 were studied experimentally. The results showed that the alcohol extraction method was superior to the water extraction method, and the resin adsorption method was significantly better than the n-butanol extraction method. The supercritical CO2 extraction method was better when methanol and a volume fraction of 95  ethanol were used as the entrainer.
