Quercetin 3,7-diglucoside
IUPAC 名称
2-(3,4-dihydroxyphenyl)-5-hydroxy-3,7-bis({[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy})-4H-chromen-4-one
描述
Quercetin 3,7-diglucoside, also known as quercetin-3,7-O-beta-diglucopyranoside or 3,7-diglucosylquercetin, 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 3,7-diglucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3,7-diglucoside can be found in a number of food items such as fenugreek, grape, safflower, and hedge mustard, which makes quercetin 3,7-diglucoside a potential biomarker for the consumption of these food products.
