| 摘 要： | 臧红T能产生特征荧光,其激发波长和发射波长分别为264nm和577nm.酸性介质中,Fenton体系(H2O2-Fe2+)产生的羟自由基能氧化臧红T使其荧光猝灭,而许多花茶的提取物可部分清除溶液中的羟自由基使其荧光猝灭程度降低,据此建立了一种测定黄山贡菊和金菊的抗氧化活性的新方法.本实验采用单因素实验法,对羟自由基体系...

| Abstract: | Characteristic fluorescence produced by safranine T was observed with its excitation and emission wavelength at 264nm and 577nm,respectively.Fluorescence intensity of safranine T was quenched by the hydroxyl free radical produced by Fenton system in acidic medium.However,this quenching effect can be alleviated by some extractants of flower tea,because the hydroxyl free radical can be partially cleaned.Based on this principle,a fluorometry method was developed for the determination of the antioxidant activit... |
