Green Tea Extract is a standardized botanical extract refined from the tender leaves of Camellia sinensis through modern extraction and purification technologies. Its core active components are tea polyphenols, of which epigallocatechin gallate (EGCG) is the most potent and representative monomer and accounts for a major share of the extract’s antioxidant and biological activity; small amounts of natural tea polysaccharides and amino acids provide synergistic effects. With excellent antioxidant, anti-inflammatory and metabolism-regulating activities, it is a versatile natural raw material widely used in health food, functional beverages, skincare products and natural preservation. A full range of standardized products is available, from 50% tea polyphenols to 98% high-purity grades and customized EGCG levels.
