Notoginsenoside R1

Notoginsenoside R1 is a ginsenoside found in Panax notoginseng, a dammarane-type triterpenoid substituted with hydroxy groups at the 3beta, 6alpha, 12beta, and 20 pro-S positions. The hydroxy groups at positions 6 and 20 are converted to beta-D-xylopyranosyl-(1->2)-beta-D-glucopyranoside and beta-D-glucopyranoside, respectively. A double bond is introduced at the 24-25 position. It functions as a plant metabolite, antioxidant, neuroprotective agent, apoptosis inducer, and phytoestrogen. It is classified as a beta-D-glucoside, 12beta-hydroxy steroid, 3beta-hydroxy steroid, disaccharide derivative, ginsenoside, tetracyclic triterpenoid, and 3beta-hydroxy-4,4-dimethylsteroid. It derives from a hydride of a dammarane.
