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.
Gallocatechin gallate (GCG) is the ester of gallocatechin and gallic acid and a type of catechin. It is an epimer of epigallocatechin gallate (EGCG). In a high temperature environment, an epimerization change is likely to occur, because heating results in the conversion from EGCG to GCG. [ 1 ]
Epigallocatechin and gallocatechin contain an additional phenolic hydroxyl group when compared to epicatechin and catechin, respectively, similar to the difference in pyrogallol compared to pyrocatechol. Catechin gallates are gallic acid esters of the catechins; an example is epigallocatechin gallate, which is commonly the most abundant ...
Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate, is the ester of epigallocatechin and gallic acid, and is a type of catechin.. EGCG – the most abundant catechin in tea – is a polyphenol under basic research for its potential to affect human health and disease.

Prodelphinidin is a name for the polymeric tannins composed of gallocatechin. [ 1 ] [ 2 ] [ 3 ] It yields delphinidin during depolymerisation under oxidative conditions. Natural occurrences
Green tea UV 280 nm chromatogram. Highest peak is caffeine, second highest is EGCG. Catechins include epigallocatechin-3-gallate (EGCG), epicatechin (EC), epicatechin-3-gallate (ECg), epigallocatechin (EGC), catechin, and gallocatechin (GC).
