| 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。 |

| 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. |
