三七叶中人参皂苷Rb3及总皂苷质量差异研究

Study on the difference of ginsenoside Rb3 and total saponins in the leaves of Panax notoginseng

目的:比较不同部位、不同生长年限、不同生长年份的三七叶中皂苷的含量,为三七叶相关产品开发和质量标准升级提供参考。方法:采用HPLC及UV法分别测定人参皂苷Rb3和总皂苷的含量。结果:人参皂苷Rb3及总皂苷主要分布于叶部,在茎和基部仅微量分布。3年生的整体质量优于2年生。不同年份采收的三七叶质量差异较大。结论:不同部位和不同生长年限的三七叶质量差异较大,采收和利用时需注意叶和茎的比例。

Objective:To compare the contents of saponins in Panax notoginseng leaves from different parts,different growth years and different year of growth,to provide a reference for the development of related products and upgrading of quality standards of Panax notoginseng leaves.Methods:The contents of ginsenoside Rb3 and total saponins were determined by HPLC and UV methods,respectively.Results:Ginsenoside Rb3 and total saponins were mainly distributed in the leaves,with only trace distribution in the stems and bases.The overall quality of the three-year-old samples was better than that of the two-year-old.The quality of Panax ginseng leaves harvested in different years varied considerably.Conclusion:The quality of Panax notoginseng leaves varied significantly between different parts and years of growth,and attention should be paid to the ratio of leaves to stems when harvesting and utilizing.
