Flavonoid-3-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. Thus, kaempferol 3-rhamnosyl-(1->3)-rhamnosyl-(1->6)-glucoside is considered to be a flavonoid lipid molecule. Kaempferol 3-rhamnosyl-(1->3)-rhamnosyl-(1->6)-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Kaempferol 3-rhamnosyl-(1->3)-rhamnosyl-(1->6)-glucoside can be found in tea, which makes kaempferol 3-rhamnosyl-(1->3)-rhamnosyl-(1->6)-glucoside a potential biomarker for the consumption of this food product.
