| Abstract: | OBJECTIVE：To optimize the purification process for the extract of Corydalis yanhusuo by comparative study.METHODS：The feasibility of 3 kinds of purification processes（ultrafiltration,ethanol precipitation and natural clarifier） was evaluated by comparing the physical character of purified samples with using the retention rate of corydalis B and the rate of removed impurity as index.RESULTS：The rate of removed impurity was the highest and the quality of samples was the best by ultrafiltration method among 3 kinds of methods.CONCLUSION：Ultrafiltration is the best purification process for the extract of C.yanhusuo. |
