Studies on the toxicity of autoxidized oils. 1. Fractionation of the toxic compound and its identification

, : Studies on the toxicity of autoxidized oils. 1. Fractionation of the toxic compound and its identification. Journal of Japan Oil Chemists' Society 21(6): 316-321

1. Methyl linoleate was autoxidized at 60 deg C and the toxicity to mice was examined. The longer the ester was oxidized, the more toxic it became. To fractionate the toxic substance, the oxidized ester was subjected to molecular distillation to separated low mol. wt. compounds. The residue was washed with dilute alkali to remove free fatty acids and then column chromatographed on silicic acid to give 4 fractions, A, B, C, D.
