Monohydroperoxides were isolated from chlorophyll-photosensitised oxidation of methyl oleate, methyl linoleate, methyl linolenate, and ethyl arachidonate. The positions of the hydroperoxide substituent were determined by two methods of analysis of the saturated hydroxy-esters formed by catalytic hydrogenation. Gas–liquid chromatographic analysis of degradation products and mass spectrometric analysis
从油酸甲酯,亚油酸甲酯,亚油酸甲酯和花生四烯酸乙酯的叶绿素光敏氧化分离出单氢过氧化物。通过两种分析由催化氢化形成的饱和羟基酯的方法确定氢过氧化物取代基的位置。降解产物的气液色谱分析和相应的酮酸酯的质谱分析均证明氢过氧化物基团位于最初形成双键一部分的每个碳原子上。
