摘要
祁门红茶有较强的抗芥花子油氧化的活性。从祁门红茶乙酸乙酯部位 ,使用硅胶柱层析 ,结合SephadexLH 2 0柱层析方法 ,分离得到了四个抗氧化有效成分 ,分别为茶黄素 (Theaflavin ,TF1)、茶黄素A(Theaflavin 3 gallate ,TF2 A)、茶黄素B(Theaflavin 3’ gallate,TF2 B)和茶黄素双没食子酸酯 (Theaflavindigallate,TF3 )。
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).
