Development of a Flow-Injection ESR System for Evaluating the Lipophilic Alkoxyl Radical Eliminating Capacities (L-AREC) of Tocopherol Analogues and Unsaturated Fatty Acids

A new lipophilic spin-trapping flow-injection electron spin resonance (LFI-ESR) system was developed for quantitative detection of DMPO spin-adduct of alkoxyl radical (RO•), which was produced by thermal decomposition of an azo-initiator (AIBN) in ethyl acetate at 70 °C. The 50% and 75% inhibition d...
