Delphinidin 3-caffeoylglucoside
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-(3,4,5-trihydroxyphenyl)-1λ⁴-chromen-1-ylium
描述
Delphinidin 3-caffeoylglucoside 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. Delphinidin 3-caffeoylglucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Delphinidin 3-caffeoylglucoside can be found in common grape, which makes delphinidin 3-caffeoylglucoside a potential biomarker for the consumption of this food product.
