AbstractA new extraction method for ginsenosides from ginseng roots, ginseng leaves and ginseng drug preparations by Sep‐Pak C18cartridges has been studied. Ginsenoside extraction by Sep‐Pak cartridges is a rapid, efficient, reproducible method. In addition, the extracts were analyzed by high performance thin layer chromatography (HPTLC) and reverse phase high performance liquid chromatography (HPLC). The major components of ginseng saponins were effectively separated using an ODS‐120T c
