Quercetin 3-O-caffeyl-glucoside
IUPAC 名称
[(2R,3S,4S,5R,6S)-6-{[2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4-oxo-4H-chromen-3-yl]oxy}-3,4,5-trihydroxyoxan-2-yl]methyl (2E)-3-(3,4-dihydroxyphenyl)prop-2-enoate
描述
Quercetin 3-o-caffeyl-glucoside is a member of the class of compounds known as flavonoid 3-o-p-coumaroyl glycosides. Flavonoid 3-o-p-coumaroyl glycosides are flavonoid 3-O-glycosides where the carbohydrate moiety is esterified 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. Quercetin 3-o-caffeyl-glucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3-o-caffeyl-glucoside can be found in caraway, which makes quercetin 3-o-caffeyl-glucoside a potential biomarker for the consumption of this food product.
