Optimization of the Ultrasonic Extraction Technology of Ganoderma Lucidum Using Response Surface Method

The purpose of the research was to determine the optimum technology and conditions of Ganoderma lucidum 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 efectively by the validation data.By analyzing the response surface plots and their corresponding contour plots as well as solving the quadratic equation,the optimum process parameters for Ganoderma lucidum Ultrasonic extraction were obtained as:ultrasonic time 43 min,ultrasonic power 650 W,the ratio of liquid to solid 1:48。
