  General description

  Catechins are phytochemicals, richly present in black grapes, peaches, strawberries and broad beans. Catechins occur in various forms such as catechins, epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate.^[1]

  Biochem/physiol Actions

  An antioxidant flavonoid of plant origin; a free radical scavenger, preventing free radical-mediated damage in a variety of biological systems. For example, at physiological pH catechin suppressed DNA strand breaks by hydroxyl radicals. It has also been shown to prevent human plasma oxidation. It delayed the consumption of endogenous lipid-soluble antioxidants and inhibited lipid oxidation.
