| Abstract: | The total flavonoids were extracted using ultrasonic extraction,selecting the liquid to solid rati-o,ethanol volume fraction and extraction time three factors design,using Box-behnken response surface methodology（ RSM）verification and optimization of process conditions. The result showed that the opti-mum condition were as follows：ethanol volume fraction is 46%,liquid to material ratio at 36：1 ,extraction time 5. 7 min. Under this condition,the extraction rate of flavonoids is 9. 42%. |
