| Abstract: | By the assistance of microwave and ultrasonic,the effects of ethanol concentration,mass ratio of Selfheal and ethanol,extraction temperature,extraction time on the extraction of ursolic acid from Selfheal were studied.The optimum extraction conditions for extraction efficiency of ursolic acid were found to be: ethanol concentration of 95%(volume),mass ratio of ethanol and Selfheal of 12∶1,extraction temperature of 70℃,extraction time of 240s respectively and extraction efficiency of 98.84% was obtained. |
| Keywords: | assistance of microwave and ultrasonic Selfheal ursolic acid extraction process |
