液质联用测定人参与五灵脂、莱菔子配伍的人参皂苷

Study on the Variation of Chemical Constituents During Combination of Ginseng with Trogopteroum Feces and Semen Raphani by High Performance Liquid Chromatography-Mass Spectrometry

采用液质联用(HPLC-ESI-MSn)技术,对不同比例的人参、五灵脂和人参、莱菔子的水煎液、沉淀和药渣进行研究,共鉴定了10种人参皂苷,并对这10种人参皂苷配伍前后的变化进行了系统的研究。实验结果表明,在共煎液中,除Ro外,其它皂苷的含量都有所下降。五灵脂或莱菔子的加入对人参皂苷的影响不同,莱菔子影响人参皂苷的溶出,而与五灵脂配伍,部分人参皂苷生成沉淀。

A high performance liquid chroatography-electrospray ionization-mass spectrometric method was developed for analysis and identification of ginsenosides from the decoction of ginseng, ginseng with trogopteroum feces and ginseng with semen raphani. Ten ginsenosides were separated and detected. The content variation of these ginsenosides was researched. The experimental results showed, that ginsenosides were less in compatible decoction than in separate one expect Ro. the stripping of ginsenosides were restrained by semen raphani and during combination of ginseng with trogopteroum feces, the precipitates were produced by ginsenosides.
