flavonoid

/fla·vo·noid/ (fla´vah-noid) any of a group of compounds containing a characteristic aromatic nucleus and widely distributed in higher plants, often as a pigment; a subgroup with biological activity in mammals is the bioflavonoids.

flavonoid

Herbal medicine
Any of a family of yellow pigments which are chemically similar to tannins and somewhat similar in use; flavonoids have been used for bruising, hay fever and menorrhagia. 

Nutrition
A family of biologically active polyphenolic compounds found in fruits (in particular in the pulp thereof), vegetables, tea and red wine, which are potent antioxidants and effective platelet inhibitors; a flavonoid-rich diet may protect against atherosclerosis and platelet-mediated thrombosis, due to flavonoids’ platelet-inhibition.

Fruits contain a wide range of phytochemicals, ranging from anthocyanins and resveratrol in dark-colored grapes, quercetin in apples, to flavanones such as hesperidin and naringin in citrus.
