Peonidin 3-(6''-caffeoyl-glucoside)
IUPAC 名称
3-{[(2S,3R,4S,5S,6R)-6-({[(2E)-3-(3,4-dihydroxyphenyl)prop-2-enoyl]oxy}methyl)-3,4,5-trihydroxyoxan-2-yl]oxy}-5,7-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-1λ⁴-chromen-1-ylium
描述
Peonidin 3-(6''-caffeoyl-glucoside) is a member of the class of compounds known as anthocyanidin 3-o-6-p-coumaroyl glycosides. Anthocyanidin 3-o-6-p-coumaroyl glycosides are anthocyanidin 3-O-glycosides where the carbohydrate moiety is esterified at the C6 position with a p-coumaric acid. P-coumaric acid is an organic derivative of cinnamic acid, that carries a hydroxyl group at the 4-position of the benzene ring. Peonidin 3-(6''-caffeoyl-glucoside) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Peonidin 3-(6''-caffeoyl-glucoside) can be found in common grape, which makes peonidin 3-(6''-caffeoyl-glucoside) a potential biomarker for the consumption of this food product.
