不同提取方法对人参皂苷提取率的影响

Effect of Different Methods on Extracting Ratios of Ginsenosides

采用回流、超声波、微波3种不同方法提取人参皂苷。结果表明:超声波、微波提取法与传统的回流提取方法相比,人参皂苷的提取率接近,分别为3 99%、3 56%、3 27%,且操作简捷。在微波提取条件下,比较了以50%乙醇、水、甲醇为提取溶剂人参皂苷的得率,结果是以50%乙醇为提取剂的人参皂苷提取率更高(5 25%),该方法为工业化提取人参皂苷提供了新途径。

Ginsenoside extraction was conducted by way of ultrasonic, microwave and circumfluence respectively The results show that ratios under ultrasonic extraction and microwave extraction are similar to that under circumfluence extraction (the traditional method), being 399%,356% and 327% respectively Under microwave extraction, the ratio of Ginsenosides with ethanal solution of 50% is higher than that of methanol solution This result will optimize the extracting method through microwave and offer a new approach to industrialization in Ginsenoside extraction as well
