Quercitrin

Quercitrin, also known as quercimelin or quercitronic acid, belongs to the class of organic compounds known as flavonoid-3-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. A quercetin O-glycoside that is quercetin substituted by a alpha-L-rhamnosyl moiety at position 3 via a glycosidic linkage. Quercitrin exists in all living organisms, ranging from bacteria to humans. Quercitrin is found, on average, in the highest concentration within a few different foods, such as lingonberries, american cranberries, and olives and in a lower concentration in common beans, tea, and welsh onions. Quercitrin has also been detected, but not quantified, in several different foods, such as guava, bilberries, common pea, apricots, and spearmints.
