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

Analysis of Caffeine and Catechins in Green Tea

Validated HPLC method (based on Ph. Eur. Monograph 2668) for quantifying catechins and caffeine in decaffeinated green tea using a Chromolith® High Resolution RP-18e column with advantages in terms of backpressure and matrix robustness.

HIF-1α plays a key role in iron uptake and transport in the liver, whose activity is tightly linked to the repression of hepcidin (Hamp). Hamp prevents intestinal iron uptake and cellular efflux by negatively modulating ferroportin. Hamp is also expressed

Long-term exposure to low doses of environmental carcinogens contributes to sporadic human breast cancers. Epidemiologic and experimental studies indicate that green tea catechins (GTCs) may intervene with breast cancer development. We have been developing a chronically induced breast cell carcinogenesis

Metabolic profiles of broiler chickens were examined after the ingestion of green tea, tea polyphenols, and (-)-epigallocatechin-3-gallate (EGCG). Solid-phase extraction of serum and litters yielded free catechins and their metabolites, which were then identified and quantified by liquid chromatography-tandem mass
