摘要
研究超声波辅助提取杜仲叶中绿原酸的工艺。在单因素和正交优化设计实验的基础上,确定了最佳提取工艺条件,提取溶剂乙醇体积分数为45%,料液比为1∶8,超声波屏极电流为0.60A,提取时间为30min,绿原酸提取率可达2.81%。该工艺具有溶剂用量较少,提取周期较短,提取率较高等特点。
In this paper, ultrasonic assisted extraction technology of chlorogenic was studied. Based on the single factor and orthogonal test the optimum technology conditions were founded as follows： the concentration of ethanol was 45%, ratio of solid to solution was 1 ： 8, operating time of ultrasonic was 30 rain. Chlorogenic acid yield of ultrasonic assisted extraction was 2.81%. This technology was good with some merits such as a small quantity of menstruum, short cycle, high extraction yield.
