Abstract
Methyl eicosapentaenoate (methyl 5,8,11,14,17-eicosapentaenoate) was subjected to autoxidation and methylene blue sensitized photooxidation. Methyl eicosapentaenoate monohydroperoxides, the primary products of the autoxidation and photosensitized oxidation, were isolated by silica gel column chromatography, and characterized by ultraviolet, infrared and nuclear magnetic resonance spectra. The isomeric composition of the monohydroperoxides were determined by gas chromatography-mass spectrometry as follows: the 5-, 8-, 9-, 11-, 12-, 14-, 15- and 18-isomers (autoxidation), and the 5-, 6-, 8-, 9-, 11-, 12-, 14-, 15-, 17- and 18-isomers (photosensitized oxidation). Methyl eicosapentaenoate was readily oxidized both by autoxidation and by photosensitized oxidation.This publication has 14 references indexed in Scilit:
