Interaction of metal, especially iron ions with flavanols is considered as an important feature of these compounds and is believed to contribute to their both antioxidant and prooxidant properties. The aim of this study was to examine how Fe²⁺ binding to form a 4:1 (flavanol:Fe²⁺) mixtures affects the antioxidant properties of flavanols. ABTS^∗ scavenging, protection against fluorescence bleaching induced by AAPH and hypochlorite, protection against lipid peroxidation and protection against hypochlorite-induced hemolysis demonstrated that flavonol-Fe²⁺ mixtures retain antioxidant properties, although, in most cases, they are lower with respect to the flavanols alone. No superoxide dismutase-like or catalase-like activity of the mixtures was revealed.

金属，特别是铁离子与黄烷醇的相互作用被认为是这些化合物的重要特征，并且被认为有助于它们的抗氧化剂和促氧化剂性质。这项研究的目的是研究Fe ²⁺结合形成4：1（黄烷醇：Fe ²⁺）混合物如何影响黄烷醇的抗氧化性能。ABTS ^∗清除，防止AAPH和次氯酸盐引起的荧光漂白，防止脂质过氧化和防止次氯酸盐引起的溶血作用均表明黄酮-Fe ²⁺混合物保留了抗氧化性能，尽管在大多数情况下，它们相对于单独的黄烷醇含量较低。没有发现混合物的超氧化物歧化酶样或过氧化氢酶样活性。
