✦ Synopsis

Oxidized oleic acid esters are separated by means of column chromatography into several fractions, the purity and composition of which may be determined either by chromatography on silicic acid impregnated paper or by thin-layer chromatography. The two methods are considered equally suitable. Autoxidized unsaturated fatty acid derivatives are complex ' mixtures ,of products. The analysis is very difficult as other oxidation products of the'. mixture, interfere with the determination of individual components. A separation of the mixture into simple fractions prior to the analysis is, therefore, tlie method of choice: ,' Oxidized. lipids are usually separated. by column chromatographyl-4 on' pdlar or non-polar adsorb.ents. The cornposition, of the fractions thus obtained is best. determined by paper or thin-layer chromatography s-s. The subj'ect of.this study was . to compare the suitability ofthese chromatographic methods, pure oleic acid esters' being used as model substances.
