Abstract: The conditions of ultrasonic extraction of antioxidants from blackberry were studied by response surface method using the removal rate of 1,1-diphenyl-2-picryhydrazyl redical(DPPH·) as evaluation index, based on single factor experiment of liquid-solid ratio, ultrasonic time,extraction temperature, ultrasonic power and ethanol volume fraction. The results showed that the optimal extraction conditions were:fresh fruits of blackberry 2.5g, liquid-solid ratio 26:1, ultrasonic temperature 52℃, ultrasonic power 160W, ethanol volume fraction 53%.Under these conditions, the removal rate of DPPH· was 67.13%.
