| 摘 要： | 中药罗汉果是广西特产,本文采用微波辅助提取技术,从罗汉果中提取罗汉果皂苷,并优化出最佳的微波提取功率、微波辐射时间、固液比及原料的粉碎度。结果表明,最佳的微波辐射时间是5min、微波功率是495W、原料的粉碎度为不小于0.15mm及固液比为1:30,和传统的加热提取相比较,微波辅助提取的提取时间短,但具有较高的提取率。微波辅助提取的提取时间为5min时,提取率达76.56%,而传统的加热提取时间为2h时,提取率为68.46%。

| Abstract: | Luohanguo(Siraitia grosvenorii) is a special agricultural product in Guangxi province. In the present study, a new method of microwave-assisted extraction(MAE) has been used to extract triterpene glucoside from Siraitia grosvenorii. 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 Siraitia grosvenorii 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 of triterpene glucoside from Siraitia grosvenorii. |
