不同时期远志地上部分总皂苷含量比较研究

Analysis of Total Saponin in Aerial Part of Radix Polygala in Different Periods

目的探索远志地上部分的开发价值。方法:采用水提醇沉获得粗提物,通过大孔树脂不同浓度醇洗脱,富集不同洗脱成分。三种鉴别反应进行定性,分光光度法对含量进行测定。结果与结论:测定结果显示,远志地上部分有皂苷成分。地上部分提取物经大孔树脂富集含量最高可以达到2.72%,具有开发价值。

Objective：The aim was to explore development value of the aerial parts of Polygala.Methods：Crude extract was obtained by water extraction and alcohol precipitation,macroporous resin by elution with different concentrations of alcohol was used to concentrate of different components eluting.After three qualitative identifications,contents of total Saponin was analyzed by spectrophotometric determination.Results or Conclusion：There have Saponin in aerial part of Polygala and the content reached 2.72% through macroporous resin.Data show that aerial parts of Polygala has development value.
