Flavones were extracted from Physalis alkekengi L. coating by ultrasonic method. Effects of material ratio, concentration of alcohol, ultrasonic time, temperature and power on the yield of flavones were studied. Optimal extracting conditions were determined through single factor and orthogonal experiments. The results showed that when ultrasonic power was 450 W, ratio of material to liquid was 1:50, the optimal extracting conditions were as follows: concentration of alcohol 50%, ultrasonic time 20 min, ultrasonic temperature 80°C, under above conditions, extraction yield of flavones was 1.93%. which approximated the predicted value of 2.05%.
