Abstract: The fatty acid composition of the seed oil of Ferulago trachycarpa Boiss., collected from two different localities (Balıkesir-Edremit and Konya-Seydişehir), was analyzed for derived methyl esters of their fatty acids by capillary gas chromatography-mass spectrometry (GC-MS). Seventeen components representing 98.7 % of Balıkesir sample and 98.6 % of Konya sample of F. trachycarpa seed oils were identified. GC-MS data showed that the main fatty acids were 9-octadeceneoic acid (68.1 and 73.6 %), 9,12-octadecadienoic acid (23.0 and 18.0 %), 9-hexadeceneoic acid (4.1 and 3.5 %) and 11-octadecenoic acid (2.0 and 1.8 %) in both oils, respectively. Unsaturated fatty acids were found as high as 97.7 and 97.4 %, while the percentage of the saturated fatty acids was found as low as 1.0 and 1.2 % in both seed oils, respectively.
