Epigallocatechin gallate (EGCG) is one of four major catechins in
green tea. Catechins belong to the flavan-3-ol class of flavonoids.
Green tea catechins are the flavan-3-ols found in green tea leaves.
All catechins including EGCG are polyphenolic substances.
Green tea catechins, especially EGCG, make up approximately thirty percent of the dry weight of green tea leaves. Of the catechins, EGCG is the most abundant one in green tea leaves. Green tea has and continues to be a popular beverage in the Orient (especially in China and Japan). In this region, it is thought to have a number of health-promoting benefits, and it is used in the management of various disorders. Clinical studies suggest that green tea may have cancer chemo preventive, as well as anti-atherogenic properties.*
The catechins in green tea are responsible for the purported health
benefits of the plant. These catechins are antioxidants, with EGCG
appearing to be the most power antioxidant of all the green tea
catechins*
