摘要
目的:提取和纯化人参皂苷Rg1,并测定其含量。方法:采用超声法提取人参总皂苷,使用硅胶柱层析法分离、纯化人参皂苷Rg1,采用高效液相色谱法测定人参皂苷Rg1含量。结果:采用硅胶柱层析分离50g人参,可得到人参皂苷Rg19.91g,其纯度为89.63%。结论:此提取方法简单、准确,成本较低,所获产品纯度较高,可作为获得人参皂苷Rg1的有效方法。
OBJECTIVE:To extract and purification ginsenoside Rg 1 and to determine the content of it.METHODS:Ultrasonic extraction was used to extract total saponin of Panax ginseng.Ginsenoside Rg 1 was separated and purified with silica gel column chromatography.HPLC method was used to determine the content of ginsenoside Rg 1.RESULTS:9.91 g ginsenoside Rg 1 was obtained with the purity of 89.63% in 50 g P.ginseng.CONCLUSION:The method is simple,accurate and low cost,and the purity is satisfied.So,this technology is suitable to prepare ginsenoside Rg 1.
