Catechins and theaflavins-the main polyphenolic substances of green and black tea, respectively-exert a plethora of beneficial effects on the cardiovascular system. In a model of H(2)O(2)-mediated oxidative stress, we investigated the effects of epigallocatechin-3-gallate (EGCG) and theaflavin-3,3'-digallate (TF3) on neonatal

Theaflavin (TF-1), theaflavin-3-monogallate and theaflavin-3'-monogallate mixture (TF-2), and theaflavin-3,3'-digallate (TF-3) are the major black tea polyphenols. Here we compared the effects of these polyphenols on cell growth, apoptosis, and gene expression in normal and cancerous cells. We showed that TF-2
