摘要
Abstract
The purpose of the present study was to optimize the ultrasonic-assisted extraction of superoxide dismutase（SOD） from bilberry leaves.Process variables such as ultrasonic power,ultrasonic treatment time and material/liquid ratio were optimized using response surface methodology on the basis of one-factor-at-a-time experiments.The results indicated that the optimal extraction conditions were ultrasonic power of 780 W,ultrasonic treatment time of 5.8 min and material/liquid ratio of 1：2.4.Under these conditions,the specific activity of SOD from bilberry leaves was 1999.28 U/mL.关键词
