Comparison of the Seed Oils of Ferulago trachycarpa Boiss. Different Localities with Respect to Fatty Acids

The fatty acid composition of the seed oil of Ferulago trachycarpa Boiss., collected from two different localities (Balikesir-Edremit and Konya-Seydisehir), was analyzed for derived methyl esters of their fatty acids by capillary gas chromatography-mass spectrometry (GC-MS). Seventeen components representing 98.7 % of Balikesir 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.
