摘　　要：目的优选百蕊草的最佳提取工艺。方法采用正交试验法,以干膏得率及山奈酚含量为指标,考察溶剂浓度、溶剂用量、提取时间以及提取次数的影响,确定最佳提取工艺。结果最佳提取工艺参数为:加8倍量80%乙醇,提取3次,每次1h。结论优选的提取工艺切实可行,可以作为百蕊草的提取工艺。Objective thogonal design was time, and extraction To optimize the extraction process of Thesium chinense Turcz. Methods The or- used to investigate the effects of solvent concentration, solvent volume, extraction frequency on yield of dry extract and content of kaempferol （as assessment indices） and to determine the optimal extraction process. Results In the optimal process, extraction was per- formed 3 times （for 1 h each time） using 80% ethanol （8 times）. Conclusion The optimized extraction process is feasible and reliable, and it can be used for extracting Thesium chinense Turcz.
