摘要-在相似的环境条件下，鸟苷- 2 - 14C和鸟苷- 8 - 14C分别被射频放电产生的单线态氧或亚甲基蓝敏化光动力反应氧化。用色谱法比较了两种情况下的反应产物。产物分布不完全相同，说明两种体系的氧化方式不同。这表明在光动力系统中ⅰ型和ⅱ型氧化机制都起作用，而在射频放电系统中只发生ⅱ型氧化反应。
Abstract— Guanosine‐2‐14C and guanosine‐8‐14C were subjected, under similar environmental conditions, to oxidation either by radiofrequency‐discharge‐generated singlet oxygen or by a methylene‐blue‐sensitized photodynamic reaction. The reaction products in both cases were compared chromatographically. The product distributions were not identical, indicating differing modes of oxidation in these two systems. It is suggested that both Type I and Type II oxidation mechanisms are operative in the photodynamic system, whereas only Type II‐like reactions occur in the radio‐frequency‐discharge system.
