The composition and contents of neutral and acidic saponins of Chinese and Japanese wildginseng were analyzed by high-performance liquid chromatography and two-dimensional thin layerchromatography. There was no significant difference in the major saponins between wild andcultivated specimens. It is noteworthy that the content of ginsenoside-Ro, the glucuronide saponinof oleanolic acid, is remarkably high in the rhizome and main root of Chinese wild ginseng.
