摘要


用微生物纸片法对抗氧化剂在生物环境中对单线态氧(1O2)的清除能力进行评价.测定了10个抗氧化剂的1O2清除能力和DPPH自由基清除能力,并从构效关系分析不同抗氧化剂1O2清除能力的不同.结果表明,该方法可以作为抗氧化剂1O2清除能力的一种常规实验室定量测定方法. A biological method, named microbiological paper method, for the evaluation of singlet oxygen (1O2) scavenging capacities of antioxidants in biological systems was proposed. The 1O2 scavenging capacities of 10 antioxidant compounds were determined. Furthermore, the results were also expounded reasonably by the structure-activity relation, and compared with those obtained by the DPPH· procedure. It was concluded that this assay could be utilized as a routine laboratory quantitative assay to evaluate the scavenging activity against 1O2.
