Common NameEpiafzelechin 3-O-gallate-(4beta->6)-epigallocatechin 3-O-gallate
DescriptionEpiafzelechin 3-O-gallate-(4beta->6)-epigallocatechin 3-O-gallate belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Epiafzelechin 3-O-gallate-(4beta->6)-epigallocatechin 3-O-gallate has been detected, but not quantified in, several different foods, such as black tea, green tea, herbal tea, red tea, and teas (Camellia sinensis). This could make epiafzelechin 3-O-gallate-(4beta->6)-epigallocatechin 3-O-gallate a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Epiafzelechin 3-O-gallate-(4beta->6)-epigallocatechin 3-O-gallate.
