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-dirhamnoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3,7-dirhamnoside can be found in medlar, which makes quercetin 3,7-dirhamnoside a potential biomarker for the consumption of this food product.
