摘　　要：目的优选延胡索最佳提取工艺。方法以延胡索乙素含量和干浸膏得率为考察指标,应用正交试验设计筛选延胡索的最佳提取工艺条件。结果药材以75%乙醇提取2次:第1次加6倍量醇,浸泡0.5h,回流提取1.5h,第2次加4倍量醇,回流提取1.5h。结论优选的最佳提取工艺稳定可行。Objective To choose the bestway of extracting procedure of Rhizoma corydalis. Methods The optimal extraction process is selected with the orthogonal design. The content of corydalis B and the yield of extracts were used to evaluate the factor levels. Results The ideal extraction process is. extracted with 75% alcohol for 2 times, first 6 times amount, soaked 0.5 h, refluxed 1.5 h, then 4 times amount, refluxed 1.5 h. Conclusions This extractive condition is the best way.
