| Abstract: | An expermient about extraction of ursolic acid from Crataegus Songorica K. Koch. with ultrasonic waves, explored the factors affecting ultrasonic extraction of ursolic acid in hawthorn. The optmium conditions of extraction procedure were ob- tained by single factor and orthogonal test. The optmium conditions were as follows： concentration of alcohol 50% ,extraction temperature 50℃, extraction power 75W, extraction tmie 50min, ratio ofsolid to liquid 1： .40. The study also showed that the ursolic acid in Crataegus Songorica K. Koch. had strong capacity for scavenging freeradicals, therefore exhibited high antioxidantactivity. |
