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.[1]
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.[2]
