摘　　要：研究了红景天有效成分的超声波提取法,通过单因素实验和正交实验,确定其优化工艺条件,并与常规热回流法作了比较。结果表明:超声波法优于常规热回流提取法。超声波法的最佳提取条件为:以H2O为溶剂、固液比为1∶10、提取时间60min。在此条件下大花红景天苷的提取率为76.11%。The extraction technology of efficacious composition in rhodiola crenulata was studied according to the single factor and orthogonal design in this paper. In comparison with the refluxing extraction technology, the result showed that the ultrasonic wave method was superior to the refluxing technology. The optimized technological process conditions were 1：10 of water to the sample weigh ratio was used with ultrasonic treatment last for 30min. The extraction rate was 76.11%.
