A flow-injection spin-trapping ESR system using DMPO (5,5-dimethyl-1-pyrroline N-oxide) was developed for quantitative detection of the alkoxy radicals (center dot OR, R = C(CH3)(2)-C(+NH2Cl-)NH2) formed by thermal decomposition of AAPH (2,2'-azobis(2,4-amidinopropane) dihydrochloride). This system was applied to estimate the alkoxy radical elimination capacity of selected antioxidants by using Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid), as a standard.
