摘要
合成茶多酚银配合物(TP-Ag)、茶多酚锌配合物(TP-Zn),采用红外光谱、紫外光谱及抗氧化活性的评价指标[油脂的过氧化值(POV)、诱导时间及抗氧化因子]对茶多酚(TP)及TP-Ag、TP-Zn抗氧化活性进行了研究。结果表明:TP-Ag、TP-Zn具有比TP更强的抗氧化活性,3者的抗氧化能力为TP-Zn>TP-Ag>TP。
In order to find out the new antioxidants that have better antioxidation ability than tea polyphenol(TP) in given condition,TP-Ag and TP-Zn complexes were synthesized and characterized by IR and UV.Their antioxidation (abilities) were investigated by IR,UV,along with determinations of peroxide value(POV),revulsive time(D) and (antioxidation) factor(F) in this paper.The results indicate that antioxidation ability of TP-Ag or TP-Zn complex is (better) than TP,the order of antioxidation ability is TP-Zn>TP-Ag>TP.The complexes are of potential application in medication and foodstuff.
