摘要
[目的]合成柚皮素金属镉配合物,并比较配合物与柚皮素的抗氧化活性.[方法]以柚皮素和乙酸镉为原料在无水乙醇溶液中制备柚皮素-镉配合物,通过紫外(UV)、红外(IR)对配合物进行表征,并采用ABTS法研究其清除自由基的能力.[结果]紫外、红外数据证实柚皮素与镉离子成功配合,且在试验浓度下,配合物对ABTS+·的清除能力随浓度增加而增强,且强于柚皮素.[结论]镉离子成功地与柚皮素形成配合物,其体外抗氧化活性较配体有所增强.
Abstract
[Objective] Naringenin-cadmium(Ⅱ) complex ( Nar-Cd) was synthesized and compared the antioxidant activity between naringe-nin and Nar-Cd.[Method]Nar-Cd complex was synthesized by using naringenin and Cd(CH3COO)2 in anhydrous ethanol solution and charac-terized by UV and IR.The antioxidant activity of Nar-Cd was evaluated by ABTS assays.[ Result] The synthesized complex was coordinated with a Cd(Ⅱ) ion by UV and IR.The scavenying activity of ABTS +· of Nar-Cd complexes was increased with concentration,and exhibited more potent antioxidation effect than naringenin.[Conclusion]Cd2 +could coordinate with the naringenin,and the antioxidation effect of the complex was stronger than the ligand.
