Southwest University of Science and Technology, M ianyang 621000, China) Abstract: In order to find out the new antioxidantst hat have better antioxidation ability than tea polyphenol( TP) in given condition, TPAg and TPZn complexes were synthesized and characterized by IR and UV. Their antioxidation abilities w ere investigated by IR, UV, along w ith determinations of peroxide value( POV) , revulsive time( D) and antioxidation factor( F) in this paper. The results indicate that ant ioxidation ability of TPAg or TPZn complex is better than TP, t he order of antioxidation ability is T PZn T PAg TP .The complexes are of potential application in medication and foodstuff.
