IUPAC 名称
3-{[(2S,3R,4S,5S,6R)-4,5-dihydroxy-6-({[(2E)-3-(3-hydroxy-4-methoxyphenyl)prop-2-enoyl]oxy}methyl)-3-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-2-yl]oxy}-7-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-5-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-1λ⁴-chromen-1-ylium
描述
Peonidin 3-feruloyl-diglucoside 5-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-feruloyl-diglucoside 5-glucoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Peonidin 3-feruloyl-diglucoside 5-glucoside can be found in sweet potato, which makes peonidin 3-feruloyl-diglucoside 5-glucoside a potential biomarker for the consumption of this food product.
