摘要
以干罗汉果为原料,在微波辐射条件下,以水为溶剂提取罗汉果皂甙,考察了微波功率、微波辐射时间、固液比、浸提时间、提取级数等因素对提取率的影响,确定的最佳提取工艺条件为:微波功率为638W,微波辐射时间为25min,固液比为1∶30,水浴浸提时间为2h,提取级数为二级。在此条件下罗汉果皂甙的提取率为90.35%。
Triterpene glucoside was extracted by water as solvent from Siraitia grosvenorii with microwave treatment. The key factors, including the microwave power, microwave irradiation time, the volume of water and the period of extraction, were studied for the extraction yield.. The optimal conditions were identified:microwave power 638W,irradiaton by microwave for 25min,the ratio of liquid to solid 30∶1, the extraction period 2h and the stages of extraction 2. The optimal extraction yield of triterpene glucoside from Siraitia grosvenorii was 90.35%.
