Abstract
Objective response surface analysis methodology(RSM) was applied to optimize the ultrasonic-assisted extraction conditions of essential oil from ginger.The single-factor experiments and Box-behnken central component experiments design were applied.Extraction time,ratio of liquid to solid and ultrasonic power were chosen as casual factors.RSM was employed to study on the effect of these factors on the yield of essential oil from ginger.The results show that extracting time 15.8 min,ratio of liquid to solid 10.03∶1,ultrasonic power 356.42 W.Validation experiments were carried out at these optimum conditions,the average yield of general flavonoids is 3.75%.The relative error between actual values and predicted values is 1.35%.It fit well the predicted values.These results demonstrated that this method is feasible.
