Description: Epicatechin is a flavan-3-ol, a type of natural phenol and antioxidant. It is a plant secondary metabolite. The name of the catechin chemical family derives from catechu, which is the tannic juice or boiled extract of Mimosa catechu (Acacia catechu L.f). l-Epicatechin can be found in cacao beans and was first called kakaool or cacao-ol. Maximilian Nierenstein was among those who proved the presence of catechin in cocoa beans in 1931. (Source: http://en.wikipedia.org/wiki/Epicatechin).
