Separation and determination of 8beta-hydroxyasterolid and perlolyrine in Codonopsis pilosula by reversed-phase high- performance liquid chromatography


Separation and determination of 8beta-hydroxyasterolid and perlolyrine in Codonopsis pilosula by reversed-phase high- performance liquid chromatography

The sesquiterpene lactone 8 beta -hydroxyasterolid was isolated from cultivated plants of this Chinese species, which is used as an alternative to Panax ginseng [P. pseudoginseng] in the treatment of breathlessness and associated weakness. Perlolyrine, an alkaloid previously isolated from C. pilosula, was synthesized and used as a reference substance for HPLC. The contents of these 2 compounds were then determined in C. pilosula and its variety modesta from different sources, C. subglobosa, C. tangshen and P. ginseng. Neither was present in C. subglobosa; perlolyrine was absent from one source of C. pilosula var. modesta and 8 beta -hydroxyasterolid from C. tangshen. Then highest perlolyrine content was found in C. tangshen (0.0019%), followed by P. ginseng (0.0010%).
