【摘要】 [Objective] To optimize the ultrasonic-assisted extraction technology of triterpenoid from Inonotus obliquus.[Method] With isopropanol as extracting solvent,the triterpenoid was extracted from I.obliquus by ultrasonic-assisted method.Taking the extraction rate of triterpenoid as an evaluation index,the extraction technology was optimized by means of single-factor experiment with treatment condition,ultrasonic power,ultrasonic frequency and ultrasonic processing time as experimental factors.[Result] The optimum ultrasonic-assisted extraction technology of triterpenoid from I.obliquus was determined as follows:ultrasonic power of 400 W,ultrasonic frequency of 30 times and ultrasonic processing time of 15 min.With the optimized technology,the extraction rate of triterpenoid was 1.06%.[Conclusion] The ultrasonic-assisted method was a kind of effective method to extract triterpenoid from I.obliquus.
