[Objectives]The research aimed to optimize the extraction method of triterpenoids from A. selengnesis. [Methods]The ultrasonic extraction of triterpenoids in A. selengnesis was optimized by single factor analysis( including infusion time,ethanol concentration,ultrasonic power,extraction time,and liquid-solid ratio) and response surface method. [Results]The optimum extracting process of triterpenoids was as follows: infusion time of 65 min,ethanol concentration of 80%,ultrasonic power of 275 W,extraction time of 30 min,and liquid-solid ratio of 34 m L/g. Under the optimized condition,the extraction content of triterpenoids reached( 18. 26 ± 0. 10) mg/g. [Conclusions] The optimized extraction had a good modal on practice in developing and utilization.
