摘　　要：目的:优选蔷薇红景天的提取工艺。方法:以乙醇浓度、溶剂用量、提取时间和提取次数为考察因素,以红景天苷含量、酪萨维含量、浸膏得率的综合评分为评价指标,采用正交试验优选蔷薇红景天的最佳提取工艺。结果:最佳提取工艺为用10倍量85%乙醇,提取3次,每次1.5h。结论:优选的工艺简单、可行,可用于蔷薇红景天的提取。OBJECTIVE： To optimize the extraction technology of Rhodiola rosea. METHODS： The extraction technology of R. rosea was optimized by orthogonal test using ethanol concentration, solvent volume, extraction time and extraction times as fac- tors with the content of salidroside and rosavin, the yield of extract as index. RESULTS： The optimum extraction process was as follows： adding 10-fold 85% ethanol, extracting for 3 times, 1.5 hours each time. CONCLUSIONS： The method is simple and fea- sible, which can be used for the extraction of R. rosea.
