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). It ranks among the most important polyphenols in green tea leaves. ECG acts as a powerful antioxidant. Researchers often study it together with EGCG for its potential benefits in human health. It shows strong antioxidant, anti-inflammatory, and metabolic effects.

Green tea catechins, including ECG, make up a large part of the dry leaf weight. They serve as key marker compounds for quality control. Manufacturers use them to standardize green tea extracts in dietary supplements, nutraceuticals, and functional foods.
Lab and preclinical studies show that ECG effectively scavenges free radicals. It also modulates important cellular pathways and works well alongside other catechins. ECG functions as an essential reference standard. Laboratories rely on it for accurate measurement and method validation when analyzing green tea products.

Planta Analytica supplies high-purity ECG as an analytical reference standard. This product helps laboratories worldwide perform precise quantification, develop reliable methods, and standardize green tea extracts.
