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-rhamnosyl-(1->2)-rhamnosyl-(1->6)-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 3-o-rhamnosyl-(1->2)-rhamnosyl-(1->6)-glucoside can be found in common sage, common thyme, italian oregano, and rosemary, which makes quercetin 3-o-rhamnosyl-(1->2)-rhamnosyl-(1->6)-glucoside a potential biomarker for the consumption of these food products.
