( )-gallocatechin
Gallocatechol or gallocatechin (GC) is a flavan-3-ol, a type of chemical compound including catechin, with the gallate residue being in an isomeric ''trans'' position. This compound possesses two epimers. The most common, (+)-gallocatechin (GC), CAS number 970-73-0, is found notably in green tea. The other enantiomer is called (−)-gallocatechin or ''ent''-gallocatechin. It was first isolated from green tea by Michiyo Tsujimura in 1934. Epigallocatechin is another type of catechin, with the gallate residue being in an isomeric ''cis'' position. It can be found in St John's wort.
