| Abstract: | Qimen black tea has strong inhibitory activity of canola oil oxidation. Four antioxidant compounds, theaflavin(TF_1), theaflavin-3-gallate (TF_2A), theaflavin-3'-gallate (TF_2B) and theaflavin digallate(TF_3),were isolated from acetic acetate extract of black tea by silica gel and sephadex LH-20 column chromatography. TF_1,TF_2A,TF_2B and TF_3 have stronger antioxidant activity than that of BHT(Butylated hydorxytoluene). |
