Qimen black tea has strong inhibitory activity of canola oil oxidation. Four antioxidant compounds, theaflavin (TF1), theaflavin-3-gallate (TF2A), theaflavin-3'-gallate (TF2B) and theaflavin digallate (TF3), were isolated from acetic acetate extract of black tea by silica gel and sephadex LH-20 column

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
