Common Name2-[(2-{[7,11-dihydroxy-1-(2-hydroxy-6-methylhept-5-en-2-yl)-3a,3b,6,6,9a-pentamethyl-dodecahydro-1h-cyclopenta[a]phenanthren-5-yl]oxy}-4,5-dihydroxy-6-(hydroxymethyl)oxan-3-yl)oxy]-6-methyloxane-3,4,5-triol
DescriptionGinsenoside C, also known as ginsenoside-RG2 or panaxoside RG2, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Ginsenoside C is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, ginsenoside C has been detected, but not quantified in, tea. 2-[(2-{[7,11-dihydroxy-1-(2-hydroxy-6-methylhept-5-en-2-yl)-3a,3b,6,6,9a-pentamethyl-dodecahydro-1h-cyclopenta[a]phenanthren-5-yl]oxy}-4,5-dihydroxy-6-(hydroxymethyl)oxan-3-yl)oxy]-6-methyloxane-3,4,5-triol is found in Gynostemma yixingense, Panax ginseng, Panax japonicus and Panax notoginseng. 2-[(2-{[7,11-dihydroxy-1-(2-hydroxy-6-methylhept-5-en-2-yl)-3a,3b,6,6,9a-pentamethyl-dodecahydro-1h-cyclopenta[a]phenanthren-5-yl]oxy}-4,5-dihydroxy-6-(hydroxymethyl)oxan-3-yl)oxy]-6-methyloxane-3,4,5-triol was first documented in 2011 (PMID: 21598542). This could make ginsenoside C a potential biomarker for the consumption of these foods.
