This text was mainly studied the response surface optimization of ultrasonic assisted extraction of flavonoids from Brucea javanica. The optimum extraction process conditions were obtained by color reaction to prove the presence of flavonoids and by response surface simulation and quantification, the optimum condition was: ethanol concentration was 90%, the ratio of liquid to solid was 10:1, and the extraction time was 2h, the total extraction rate was the largest, up to about 1.43%.
