Polyphenols always have heteroatom substituents other than hydroxyl groups; ether and ester linkages are common, as are various carboxylic acid derivatives ( see theaflavin gallate image ); ester linkages are common in the hydrolyzable tannins.

Fujiki reported that one of those polyphenol antioxidants, called epigallocatechin gallate blocked a gene so that the cells of mice no longer expressed TNF-alpha ( tumor necrosis factor-alpha ), a known cancer cause.

Polyphenols found in green tea include but are not limited to epigallocatechin gallate ( EGCG ), epigallocatechin, epicatechin gallate, and epicatechin; flavanols such as kaempferol, quercetin, and myricitin are also found in green tea.

Specifically, agents that may decrease oxidative stress have been considered and tested in animal models, including antioxidants like (-)-Epigallocatechin-3-gallate ( EGCG ), the most abundant polyphenol in green tea.

Prodelphinidin B-2 3'- O-gallate can be found in green tea leaves and prodelphinidin B-2 3, 3'- di-O-gallate can be found in " Myrica rubra ".

Prodelphinidin B-2 3'- O-gallate can be found in green tea leaves and prodelphinidin B-2 3, 3'- di-O-gallate can be found in " Myrica rubra ".

Epigallocatechin gallate ( EGCG ), a catechin in green tea, binds to gp120, which works in conjunction with gp41, itself blocked by TF-3 ( a theaflavin ), both receptors of which HIV hijacks to enter into healthy human immune cells.
39.
Significant progress has been reported on polyphenols, particularly ellagic acid, prodelphinidin-type tannins, such as prodelphinidin B-2 3, 3'- di-O-gallate, and anthocyanins, antioxidant activity, anti-cancer and anti-viral properties.

The cardinal antioxidative ingredient in the green tea extract is green tea catechins ( GTC ), which comprise four major epicatechin derivatives; namely, epicatechin ( EC ), epigallocatechin ( EGC ), epicatechin gallate ( ECG ), and epigallocatechin gallate ( EGCG ).
