(-)-epicatechin-3-O-gallate is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of epicatechin. A natural product found in Parapiptadenia rigida. It has a role as a metabolite, an EC 3.2.1.1 (alpha-amylase) inhibitor and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a catechin, a gallate ester and a polyphenol. It is functionally related to a (-)-epicatechin and a gallic acid. (-)-Epicatechin gallate is a natural product found in Scurrula atropurpurea, Acacia omalophylla, and other organisms with data available. Isolated from tea and numerous other plant subspecies inc. rhubarb and grapes. Epicatechin 3-gallate is found in many foods, some of which are cucumber, muskmelon, black raspberry, and cashew nut. A gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of epicatechin. A natural product found in Parapiptadenia rigida. (-)-Epicatechin 3-O-gallate is found in almond. (-)-Epicatechin 3-O-gallate is isolated from tea and numerous other plant species including rhubarb and grapes.
