绞股蓝总皂苷的闪式提取及纯化工艺研究 刘振洋1,赵余庆2* (1.辽宁中医药大学,沈阳110032; 2. 沈阳药科大学, 沈阳 110016) [摘要]:目的:研究和优选绞股蓝总皂苷的提取和纯化工艺。方法:以绞股蓝总皂苷的含量为测定指标,采用分光光度法测定和比较不同提取纯化工艺后绞股蓝总皂苷的含量。结果:闪式提取和乙醇回流提取所得绞股蓝总皂苷含量分别为32.69%,31.19%;经过D-101和HPD-100树脂纯化后的绞股蓝总皂苷含量分别为81.9%,82.7%。结论:采用闪式提取和D-101、HPD-100树脂纯化是可行的绞股蓝总皂苷提取纯化工艺。 [关键词]:绞股蓝;绞股蓝总皂苷;闪式提取法;提取工艺;纯化工艺;树脂 Study on the Herbal Blitzkrieg Extraction and Purification Process of Total Saponins in Gynostemma pentaphyllum Liu Zhenyang 1,Zhao Yuqing2 (1.Liaoning University of Traditional Chinese Medicine,Shenyang,110032,China; 2.Shenyang Pharmaceutical University, Shenyang, 110016, China.) Abstract: Object To study and optimize the extraction and purification techniques of total saponins in Gynostemma pentaphyllum. Methods Take the content of total Saponins in Gynostemma pentaphyllum as mark, determine and compare the content of total Saponins that was determined by spectrophotometric method through the different Extraction and Purification Process. Results With Herbal Blitzkrieg Extraction to extract, the content of total Saponins is 32.69%, with ethanol refluxing the content of total Saponins is 31.19%; Purified by D-101 and HPD-100 macroporous absorption resin, the content of total saponins was above 80%. Conclution The method of using Herbal Blitzkrieg Extraction to extract and purified by D-101 and HPD-100 macroporous absorption resin is a feasible extraction and purification process of total saponins in Gynostemma pentaphyllum.
