Gas chromatographic properties of cyclic dienoic fatty acids formed in heated linseed oil

Abstract

Cyclic dienoic fatty acids isolated from heated linseed oil were examined by capillary gas chromatography on a variety of stationary phases. Equivalent chain lengths were determined for CP-Wax 52CB, BPX70, CP-Sil 84 and OV-275 phases. Not all cyclic dienes could be resolved on any one column. Identification and quantification of all components was possible only by analyses on CP-Wax 52CB together with BPX-70 or CP-Sil 84 columns.
