| Description | (-)-Epigallocatechin 3-(3-methyl-gallate), also known as 3-O-(3-O-methylgalloyl)epigallocatechin or egcg3''me, belongs to the class of organic compounds known as catechin gallates. These are organic compounds containing a gallate moiety glycosidically linked to a catechin (-)-Epigallocatechin 3-(3-methyl-gallate) is found, on average, in the highest concentration within a few different foods, such as teas (Camellia sinensis), red tea, and herbal tea and in a lower concentration in green tea and black tea. This could make (-)-epigallocatechin 3-(3-methyl-gallate) a potential biomarker for the consumption of these foods. epigallocatechin-3-O-(3'-O-methyl)gallate is found in Camellia sinensis and Limonium sinense. epigallocatechin-3-O-(3'-O-methyl)gallate was first documented in 1996 (Davis, A. L., et al.). Based on a literature review very few articles have been published on (-)-Epigallocatechin 3-(3-methyl-gallate). |
