Fluoro fatty acids in seed oil of Dichapetalum toxicarium

Abstract

The fatty acid composition of the seed oil of Dichapetalum toxicarium was examined by GC-mass spectrometry. The presence of ω-fluoro-palmitoleic, -stearic, -linoleic, -arachidic and -eicosenoic acids was established, in addition to that of the ω-fluoro derivatives of oleic and palmitic acids previously isolated from this source. Strong evidence was also obtained for the presence of 18-fluoro-9,10-epoxystearic acid.
