General description

Gallocatechin belongs to the catechin class of organic compounds and is one of the major components of green tea. The beneficial effects of catechins include anti-tumorigenic, anti-mutagenic, anti-pathogenic, and anti-oxidative properties.

Application

(−)-Gallocatechin may be used as an analytical standard for the determination of the analyte in biological fluids and tea beverages by chromatography-based techniques.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
