三七叶与茎HPLC的比较分析及Rb3含量的测定

目的：比较三七叶和三七茎的皂苷成分，为叶苷相关产品的质量提供技术保障。方法采用HPLC，对三七叶和三七茎的皂苷成分进行比较，其中主要以人参皂苷Rb3、Rb1的含量为考察指标。结果三七叶中主要成分为Rb3，其中三个产地的三七叶中Rb3平均含量为1.025%.三七茎秆中以Rb1为主，Rb3微量。结论三七叶和三七茎中主要皂苷成分有显著的差异，为保证叶苷产品的质量稳定，应重视生产原料的选择，控制三七叶和茎的比例。

Comparative Analysis and Quantitative of Rb3 Leaves and Stems of Panax notoginseng by HPLC

Objective Comparison of the Saponins content of Panax notoginseng stems and leaves, and to provide technical support for the quality of related products. Methods Rb3 content was used as indicator to compare the difference between the leaves and stems of Panax notoginseng by HPLC. Results The leaves’ main components are Ginsenoside Rb3, Rc, Fc, et al. and the stems’ main component is Ginsenoside Rb1. Conclusion The main saponin components in leaves and stems have significant difference, in order to ensure the stable quality of product we should pay attention to the selection of raw material, control the proportion of leaf and stem of Panax notoginseng.
