摘　　要：为优化灵芝超声波提取工艺,在单因素试验基础上,采用响应面法建立灵芝超声波提取方法的二次多项数学模型,并验证该模型的有效性;探讨超声波时间、超声波功率、料液比3个因子的交互作用及其最佳水平。研究结果表明:超声波时间、超声波功率和料液比显著影响灵芝的超声波提取效果,优化灵芝超声波提取条件是:超声波时间43min,超声波功率650W,料液比1:48。The purpose of the research was to determine the optimum technology and conditions of Ganoderma lu- cidum Ultrasonic extraction by using the response Surface method （RSM）. Response surface method was employed and asecond order quadratic mathematical model for Ganoderma lucidum ultrasonic extraction was established. Its validity was verified, the alternate action of above three flactors and its optimum level range were also investigated. Results showed that ultrasonic time, ultrasonic power, and the ratio of liquid to solid were important factors. The applicability of the model equation for predicting the optimum response values was verified efeetively by the validation data. By analyzing the response surface plots and their corresponding contour plots as well as solving the quadratic equation, the optimum pro- cess parameters for Ganodema lucidum Ultrasonic extraction were obtained as： ultrasonic time 43 min, ultrasonic power 650W, the ratio of liquid to solid 1：48.
