Cis-5-monoenoic fatty acids of Carlina (Compositae) seed oils

Abstract

Seed oils of Carlina corymbosa L. and C. acaulis L. contain cis-5-octadecenoic acid as a major fatty acid (21-24%). This acid has not been previously reported as a constituent of Compositate seed oils. The predominant fatty acid in the Carlina oils is linoleic (50-52%); lesser amounts (≦10% each) of palmitic, stearic and oleic acids are also present. The oil of C. acaulis has almost 2% of cis-5-hexadecenoic acid;C. corymbosa oil includes minor amounts of some oxygenated fatty acids. © 1969 American Oil Chemists' Society.
