(2S,3R,4R,5R,6S)-2-{[2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4-oxo-4H-chromen-3-yl]oxy}-4,5-dihydroxy-6-methyloxan-3-yl acetate
描述
Quercetin 3-o-acetyl-rhamnoside is a member of the class of compounds known as flavonoid-3-o-glycosides. Flavonoid-3-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. Quercetin 3-o-acetyl-rhamnoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3-o-acetyl-rhamnoside can be found in common grape, highbush blueberry, rubus (blackberry, raspberry), and summer grape, which makes quercetin 3-o-acetyl-rhamnoside a potential biomarker for the consumption of these food products.
