Abstract
ECG (Epicatechin Gallate, CAS 1257-08-5), also known as (−)-epicatechin-3-gallate, is a major bioactive catechin found in green tea (Camellia sinensis). As one of the primary polyphenols in green tea, ECG contributes significantly to the antioxidant profile of the leaf and is frequently studied alongside EGCG for its potential roles in supporting human health research, including antioxidant, anti-inflammatory, and metabolic applications.
Green tea catechins, including ECG, typically constitute a substantial portion of the dry leaf weight and are key markers for the standardization and quality control of green tea extracts used in dietary supplements, nutraceuticals, and functional foods. In vitro and preclinical research has explored ECG’s ability to scavenge free radicals, modulate cellular pathways, and exhibit complementary bioactivity to other catechins. ECG is an important reference compound for accurate quantification and method validation in laboratories analyzing green tea products.
Planta Analytica provides high-purity ECG as an analytical reference standard to support precise quantification, method development, and extract standardization worldwide.
