IUPAC 名称
2-(3,4-dihydroxyphenyl)-5-hydroxy-3-{[(2S,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-7-{[(2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy}-4H-chromen-4-one
描述
Quercetin 3-galactoside 7-rhamnoside is a member of the class of compounds known as flavonoid-7-o-glycosides. Flavonoid-7-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Quercetin 3-galactoside 7-rhamnoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3-galactoside 7-rhamnoside can be found in broad bean, fruits, and root vegetables, which makes quercetin 3-galactoside 7-rhamnoside a potential biomarker for the consumption of these food products.
