In order to study the extraction technology condition of flavonoids from leaves of Phyllanthus emblica by ultrasonic-assisted extraction, four factors (material-liquid ratio, ethanol concentration, ultrasonic treatment time and ultrasonic powers) were investigated in the single factor experiments. The process parameters were optimized by response surface analysis method. The optimum extraction conditions of P. emblica leaves flavonoids were determined as: material-liquid ratio 1∶73, ethanol concentration 50%, ultrasonic times 30 min and ultrasonic powers 210 W. Under this condition, the extraction rate of flavonoids was 19.51%.
