以支撑磷脂双层膜(supported bilayer lipid membrane,s-BLM)作为生物膜模型,利用Fenton体系产生羟自由基(hydroxyl free radical,·OH),采用循环伏安法研究了s-BLM与·OH之间的相互作用。结果表明:具有还原基团的抗氧化剂诃子精多酚和茶多酚可通过与·OH发生氧化还原反应,可抑制·OH与s-BLM的相互作用,降低·OH对s-BLM结构的破坏程度。
The bilayer lipid membrane (s-BLM) was used as biofilm model to generate hydroxyl free radicals (OH) by Fenton system. The cyclic voltammetry was used to study the effect of s-BLM and · OH interaction between. The results showed that the polyphenols of polymyxa polyphenols and tea polyphenols with reducing group could inhibit the interaction between · OH and s-BLM through the redox reaction with · OH, reducing the effect of · OH on s-BLM structure destruction level.
