摘要/Abstract

摘要： 应用HPLC 定量分析方法, 对三七(Panax notoginseng) 地下部位的皂甙成分进行分析, 通过比较人参皂甙Rg1 , Rb1 , Re , Rd 和三七皂甙R1 等5 种主要皂甙成分和总皂甙的含量变化, 探讨不同部位和组织中皂甙成分的分布规律。结果表明: 在三七药材的不同商品等级中, 人参皂甙Rg1 和Rb1 的含量以主根60 头为最高, 5 个主要皂甙的总含量也明显高于其他的等级; 根茎的生物产量只为全根的18% , 皂甙含量占25%以上; 主根和根茎中韧皮部的生物产量和总皂甙的含量均高于木质部; 二年生三七的生物产量及皂甙含量均较三年生三七低得多。不同表型三七的皂甙组成也有区别。

Abstract: In order to elucidate the distribution rule of saponins in Panax notoginseng, the contents of ginsenosides Rg1, Re, Rb1, Rd and notoginsenoside R1 in different underground parts of notoginseng were determined by HPLC analysis. The results indicated that the contents of ginsenosides Rg1 and Rb1 together
with total content of ginsenosides Rg1, Rb1, Rd, Re, notoginsenoside R1 in the taproot“60 Tou”(viz . 60 taproots per 500 g) are highest among all commercial grades of P. notoginseng. The rhizome provided more than 25% saponins, though its biomass is only about 18% of the underground parts. The levels of biomass and saponins of phloem in both taproot and rhizome are significantly higher than those of xylem. The biomass and saponin levels of two years old roots are markedly lower than those of three years old one. The comparative analyses were carried out on P. notoginseng of different stem colors .
