Abstract The C 18 monoenoic acids in Picramnia sellowii Planch. seed oil include both cis ‐and trans ‐6‐octadecenoic acids, as well as oleic acid. The hexadecenoic acids are also the cis ‐ and trans ‐Δ6‐isomers, and the eicosenoic acids have Δ6‐unsaturation of undetermined geometric configuration. The C 18 polyenoic acids detected are 9,12‐ and 6,9‐octadecadienoic and 9,12,15‐ and 6,9,12‐octadecatrienoic acids. Partial investigation of another species, P. pentandra Sw., revealed its oil to have a similar fatty acid composition.
