Description: Tea polyphenol, also called green tea extract, are a mixture of chemical compounds, such as flavanoids and tannins, found naturally in tea. These chemical compounds are believed to be beneficial to human health, and they are the basis of many claims made about the health benefits of tea. Polyphenols are powerful antioxidants, which can reduce the risk of developing coronary artery disease and a number of other health problems. The compounds found in tea have also been linked with cancer reduction.

Additional Information

The composition of the tea leaves depends on a variety of factors, including climate, season, horticultural practices, and the type and age of the plant. The chemical composition of green tea is similar to that of the leaf. Green tea contains polyphenolic compounds, which include flavanols, flavandiols, flavonoids, and phenolic acids and account for 30% of the dry weight of green tea leaves. Most of the polyphenols in green tea are flavanols, commonly known as catechins; the major catechins in green tea are (2)-epicatechin, (2)-epicatechin-3-gallate, (2)-epigallocatechin, and (2)-epigallocatechin-3-gallate (EGCG). In black teas, the major polyphenols are theaflavin and thearubigin. 
Major chemical compositions in tea polyphenol:
(-)-epicatechin (EC):  (2R,3R)-2-(3,4-dihydroxyphenyl)chroman-3,5,7-triol
(-)-epicatechin-3-gallate (ECG): (2R,3R)-2-(3,4-dihydroxyphenyl)-5,7-dihydroxychroman-3-yl 3,4,5-trihydroxybenzoate
(-)-epigallocatechin (EGC): (2R,3R)-2-(3,4,5-trihydroxyphenyl)chroman-3,5,7-triol
(-)-epigallocatechin-3-gallate (EGCG): (2R,3R)-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)chroman-3-yl 3,4,5-trihydroxybenzoate
