摘　　要：以绞股蓝为原料,研究微波干法辅助提取绞股蓝总皂苷的新工艺。通过正交试验,得出微波处理最佳工艺参数为:功率800W、100%微波、辐射时间2min。在此条件下,经微波预处理70%乙醇快速浸泡提取,所得的绞股蓝总皂苷提取率为8.37%。与传统的乙醇回流提取法进行比较,发现微波干法辅助提取绞股蓝总皂苷提取时间缩短了近9h,提取率提高了15.8%。Introduced the extracting method of total saponins from gynostemma by microwave dry process. And the optimum microwave treating condition was gotten with the orthogonal test. The optimal technological parameters were： microwave power 800 W, 100% microwave, time 2 min. Under the condition, the extraction yield was 8.37% through microwave pretreatment and 70% ethanol rapid immersion extraction. Comparing with ethanol refluxing extraction, the extraction time decreased 9 h with microwave dry process, and the yield increased 15.8%.
