(-)-ECG-3''-O-ME Usage And Synthesis

Uses

(-)-Epicatechin 3-(3-O-methylgallate) is a catechin, that can be isolated from tea leaf. (-)-Epicatechin 3-(3-O-methylgallate) shows anti-inflammatory activity[1][2].

Definition

ChEBI: Epicatechin 3-O-(3'-O-methylgallate) is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of epicatechin. It has a role as a Camellia sinensis metabolite and an anti-inflammatory agent. It is a member of flavans, a gallate ester, a polyphenol and a monomethoxybenzene. It is functionally related to a (-)-epicatechin.
