Ginsenoside Rg2 is a ginsenoside found in Panax species, a dammarane-type triterpenoid substituted with hydroxy groups at the 3beta, 6alpha, 12beta, and 20 pro-S positions. The hydroxy group at position 6 is converted to alpha-L-rhamnopyranosyl-(1->2)-beta-D-glucopyranoside, and a double bond is introduced at the 24-25 position. It functions as a plant metabolite, cardioprotective agent, and anticoagulant. It is classified as a beta-D-glucoside, 12beta-hydroxy steroid, 3beta-hydroxy steroid, ginsenoside, tetracyclic triterpenoid, disaccharide derivative, 20-hydroxy steroid, and 3beta-hydroxy-4,4-dimethylsteroid. It derives from a dammarane hydride.
