Particularly abundant flavanoids in foods are catechin (tea, fruits), hesperetin (citrus fruits), cyanidin (red fruits and berries), daidzein (soybean), proanthocyanidins (apple, grape, cocoa), and quercetin (onion, tea, apples).Phenolic acid include caffeic acidLignans are polyphenols derived from phenylalanine found in flax seed and other cereals.
