[Objectives] To study the optimal extraction process of total flavonoids in Rhodiola rosea L., and further facilitate the development and utilization of Rhodiola rosea L. [Methods] With Rhodiola crenulata as raw material, ethanol as extractant, ultrasonic extraction as the extraction method, the single factor method was first used for preliminary investigation of effect of ethanol volume fraction, solid-liquid ratio, extraction temperature and extraction time on the flavonoids extraction rate, and then the Box-Behnken response surface method was used to optimize the extraction process of total flavonoids in R. crenulata. [Results] The optimal extraction conditions: ethanol concentration of 72%; solid-liquid ratio of 1-43; extraction temperature of 66; extraction time of 50 min. Under these conditions, the extraction rate of total flavonoids from R. crenulata was 2.591%. [Conclusions] The results showed that the method of response surface was reasonable and feasible for the optimization of ultrasonic extraction of total flavonoids from R. crenulata.
