Ginsenosides or panaxosides are a class of natural product steroid glycosides and triterpene saponins. Compounds in this family are found almost exclusively in the plant genus Panax (ginseng), which has a long history of use in traditional medicine that has led to the study of pharmacological effects of ginseng compounds. As a class, ginsenosides exhibit a large variety of subtle and difficult-to-characterize biological effects when studied in isolation. Ginsenosides can be isolated from various parts of the plant, though typically from the roots, and can be purified by column chromatography. The chemical profiles of Panax species are distinct; although Asian ginseng, Panax ginseng, has been most widely studied due to its use in traditional Chinese medicine, there are ginsenosides unique to American ginseng (Panax quinquefolius) and Japanese ginseng (Panax japonicus). Ginsenoside content also varies significantly due to environmental effects. The leaves and stems have emerged as a more abundant and easier-to-extract source of ginsenosides. Ginsenosides have also been found in jiaogulan, making jiaogulan the first plant outside of Araliaceae to contain ginsenosides.
