Separation of Tea Catechin Oxy polymers by High Performance Liquid Chromatography

LI Chun mei, XIE Bi jun [WT6BX](Department of Food Science and Technology, Huazhong Agriculture University, Wuhan 430070, China)  
Tea catechin oxy polymers were obtained by oxidizing tea catechin with H 2O 2 and their isolation conditions of HPLC were studied MS showed that their molecular weight range from 906 4 to 1962 4, which suggested that they might be dimer to pentamer of EGCG; Isocratic and linear gradient elution could not separate them from each other, but a method of combining linear and step gradients elution could separate them from each other This HPLC method might provide a new way to separate oxy polymers of catechin
