The ultrasonic-assisted extraction process of total phenol from Sophora flavescens was studied using Box-Benhnken center composite design and response surface methodology (RSM). Based on the experiment of single factor, the impacts of ethanol concentration, extraction time, ratio of liquid to solid, extraction temperature and interaction among them on extraction rate of total phenol was studied by RSM. The result suggested that the optimum extraction conditions were as follow:ethanol concentration of 44.20%, extraction time of 29.50 min ratio of liquid to solid of 32.50∶1(mL/g), and extraction temperature of 57.00℃. Under these conditions, the practical yield of total phenol reached to 4.51%.
