Microwave Extraction of Triterpene Glucoside from Fructus Leonuri

摘要：

　　In the present study,a new method of microwave-assisted extraction(MAE) has been used to extract triterpene glucoside from Fructus Leonuri.Various experimental conditions,such as microwave radiation time,microwave power,liquid/solid ratio and grinding degree of material were investigated.Optimal conditions of MAE of triterpene glucoside were determined as:duration of microwave radiation 5min,microwave power 495W,size of raw material less than 0.15mm,and ratio of liquid to solid 30:1.Comparing with conventional heating extraction,MAE of triterpene glucoside from Fructus Leonuri showed advantages of less time and high extraction rate.The time used with MAE is only 5 min with 76.56% extraction rate,while the conventional extraction method took two hours with about 68.46% extraction rate.This novel method is suitable for fast extraction oftriterpene glucoside from Fructus Leonuri.
