abstract: An integrated methodology for the identification and quantification of linoleic acid hydroperoxides (HPODEs) mixtures, obtained by the Fenton's reaction and by enzymatic oxidation, is reported. Unambiguous identification of the HPODEs formed (13-hydroperoxy-(9Z,11E)-octadecadienoic acid, 13-hydroperoxy-(9E,11E)-octadecadienoic acid and 9-hydroperoxyoctadecadienoic acid) was performed by HPLC-MS/MS analysis, while quantification was carried out by HPLC-UV using an external calibration, based on the collection of chromatographic peaks, and measuring of total hydroperoxides by ferrous oxidation-xylenol orange (FOX) method.
