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