Upper classes : FL Flavonoid : FL6 Flavan : FL63 Flavan 3-ol :  FL63AG Gallocatechin and Epigallocatechin (23 pages) :  FL63AGNS Simple substitution (17 pages)

Gallocatechins refer to a subgroup of Flavan 3-ol derivatives (FL63AG). Compared to catechins, they have an additional phenolic hydroxyl group. Catechin gallates are gallic acid esters of the catechins, and (-)-Epigallocatechin gallate (EGCG) is the most abundant catechin in green tea but not in black tea.
