摘　　要：本文以蓖麻籽为原料,超声波辅助提取蓖麻蛋白。通过单因素试验和Box-Behnkens试验及响应面分析方法对提取工艺条件进行优化。结果表明;最优提取条件为:超声波时间22min、料液比1:67、pH值7.4和超声波功率160W,在此条件下蓖麻蛋白提取率84.06%。Optimized conditions for ricin extraction process.Ricin was extraeted from castor seeds with uhrasound wave. By using single-factor experiments, the Box-Behnkens and response surface method, extration process conditions were optimized. Optimal condition were as followed ： extraction time 22rain, liquid ratio l：67, pH7.4, ultrasonic power 160 W. Under this condition, extraction yield of ricin reached 84.06%.
