What are Flavanols?
Examples are catechin and epicatechin. You may have heard of the benefits of tea. Some of them are due to gallic acid, which is combined with epicatechin. Flavonols constitute 30% of dry matter from tea solutions. In fruits, legumes and grains, they exist as condensed polymers and are concentrated more in immature fruits. Fruits stored over winter lost approximately half their content.
