Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived fromquercetum (oak forest), after Quercus.
It is a naturally-occurring polar auxin transport inhibitor.Quercetin is the aglycone form of a number of other flavonoid glycosides, such as rutin and quercitrin,found in citrus fruit, buckwheat and onions. Quercetin forms the glycosides quercitrin and rutin together with rhamnose and rutinose, respectively. Likewise guaijaverin is the 3-O-arabinoside, hyperoside is the 3-O-galactoside,isoquercitin is the 3-O-glucoside and spiraeoside is the 4'-O-glucoside. CTN-986 is a quercetin derivative found in cottonseeds and cottonseed oil. Miquelianin is the quercetin 3-o-β-d-glucuronopyranoside.
