Webtheasinensin A. ChEBI ID. CHEBI:9518. Definition. A biflavonoid that is obtained by coupling of two molecules of (−)-epigallocatechin 3-gallate resulting in a bond between positions C-2 of the hydroxyphenyl ring. It is a natural product found in oolong tea. Stars. WebNov 19, 2009 · Oxidation of EGC proceeds rapidly and, as mentioned above, the major oxidation product is dehydrotheasinensin C while proepitheaflagallin is the minor product. In contrast, oxidation of (+)-GC is slow and the major product is a 2,3-trans analog of proepitheaflagallin . Only a small amount of the dehydrotheasinensin-type product was …
