近两年来,江西省林业科学研究所等单位在全省进行了绞股蓝资源调查,结果表明绞股蓝在全省各地都能生长,但由于种的不同、生长地区不同和生长发育阶段不同,其皂甙含量有很大差异。该省有些地方绞股蓝的皂甙含量相当于人参总皂甙的30%以上,所含人参活性物质比广东、福建从日本引进的绞股蓝高35.9～54.0%,但有的地方的含量仅为人参总皂甙的2%。皂甙含量的差异与纬度及海拔高无显著相关性。
In the past two years, Jiangxi Province Institute of Forestry Science and other units conducted a survey of Gynostemma pentaphyllum resources in the province, the results show that Gynostemma can grow all over the province, but due to different species, growth areas and different stages of growth and development, the saponin content There are big differences. In some parts of the province, the content of gypenosides is equal to more than 30% of the total ginsenosides, which contains 35.9-54.0% more ginseng active substance than that of gypenosides imported from Japan and Fujian. However, the content of ginsenosides in other places is only 2%. There was no significant correlation between the content of saponin and latitude and altitude.
