**6. Role of catechin in cancer mechanisms**

The term catechins are commonly used to refer to the family of flavonoids and the subgroup flavan-3-ols or simply, flavanol. Catechins are differentiated from the ketone-containing flavonoids such as quercetin and rutin, which are called flavonols. High concentrations of catechin can be found in fresh tea leaves, red wine, broad beans, black grapes, apricots, and strawberries [45].
