quer·ce·tin

(kwer'sĕ-tin),
An aglycon of quercitrin, rutin, and other glycosides; occurs usually as the 3-rhamnoside; used in the treatment of abnormal capillary fragility.
Synonym(s): meletin, sophoretin

quercetin

(kwûr′sĭ-tĭn)
n.
A yellow powdered crystalline compound, C15H10O7, occurring as a glycoside in the rind and bark of numerous plants or synthesized and thought to have antihistaminic, anti-inflammatory, and antitumor properties.

quercetin

The flavonoid alglucon of quercitrin, or rutin, and other glycosides, which is a widely distributed antioxidant present in fruits and vegetables, such as broccoli, Brussels sprouts, cabbage and oranges, as well as in rinds, barks, clover blossoms and pollen. Early data indicates that quercetin has antiviral, anti-inflammatory, and anticarcinogenic activity; it has been used for fibromyalgia, metabolic syndrome and as a monoamine oxidase inhibitor.
