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.
