超声波辅助提取甜葫芦中葫芦素E的工艺研究

Research on the Ultrasonic Assisted Extraction of Cucurbitacin E in Sweet Gourd

对超声波辅助提取甜葫芦中葫芦素E的工艺进行研究。在单因素试验的基础上,通过正交试验优化葫芦素E的提取条件。确定甜葫芦中葫芦素E超声波辅助提取的最佳工艺为:料液比为1∶10(g/mL),甲醇体积分数为70%,提取时间为15 min,超声波功率500 W,此条件下的葫芦素E得率为0.695%。

The extraction technology with ultrasonic of cucurbitacin E from sweet gourd was studied, based on the single factor experiment, the extraction conditions with ultrasonic that has been optimized by orthogonal analysis were as follows ： the rate of solid to solution was 1 ： 10 （g/mL）, the concentration of methanol 70 %, the extraction time 15 rain ,the ultrasonic power was 500 W ,the yields of cucurbitacin E were respectively 0.695 %
