应用辣根过氧化物-鲁米诺-过硼酸钠-对碘酚增强化学发光体系测量了四种抗氧化剂清除苯氧自由基的能力,并与其清除超氧阴离子和抗鼠肝微粒体脂质过氧化的能力相比较,结果表明,这四种抗氧化剂在不同系统中都有明显的抗氧化能力,抗氧化剂清除苯氧自由基比清除超氧阴离子的能力更接近于抗鼠肝微粒体脂质过氧化的能力,从而提示增强化学发光法在测定抗氧化剂的抗氧化能力上有良好的应用前景。
Application of horseradish peroxides - luminol - sodium perborate - p - iodophenol enhanced chemiluminescence system was measured four antioxidants ability to scavenge phenoxy radicals, and its scavenging superoxide anion and anti-rat liver microsomal lipid Compared with the ability of peroxidation, the results showed that these four antioxidants have obvious anti-oxidation ability in different systems. Antioxidant scavenging phenoxy free radical is more close to anti-mouse liver microsomal fat than scavenging superoxide anion Peroxidation ability, suggesting that enhanced chemiluminescence in the determination of antioxidants antioxidant capacity has a good prospect.
