Chemical compound
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 .
