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.[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]
