Identification of the Several New Radicals Formed in the Reaction Mixture of Oxidized Linoleic Acid with Ferrous Ions using HPLC-ESR and HPLC-ESR-MS

Pages 939-945 | Published online: 07 Jul 2009
 

Abstract

ESR, HPLC-ESR and HPLC-ESR-MS analyses were performed for the reaction mixtures of oxidized linoleic acid with ferrous ions combined use of spin trapping technique. More than 14 peaks were detected on the HPLC-ESR elution profile. In addition to 7-carboxyheptyl and pentyl radicals, several new radicals such as 7-carboxy1dihydroxyheptyl, 1,5-dihydroxypentyl, 8-carboxy-1-hydroxyoctyl, 7-carboxy-1-hydroxyheptyl, 1-hydroxypentyl and 1-hydroxyhexyl were identified using HPLC-ESR and HPLC-ESR-MS.
