epicatechin

A natural plant phenol antioxidant (phytochemical) in a cis configuration, found in green tea and chocolate. It is a strong antixoidant and insulinomimetic, which reduces lipid peroxidation, inhibits platelet aggregation, controls vasodilation by regulating nitric oxide, and is thought to improve cardiac efficiency.
