Abstract: | The fatty acid composition of fixed oils obtained from the seeds of 10 species of Nigella (Nigella orientalis L., Nigella oxypetala L., Nigella latisecta P.H. Davis, Nigella segetalis Bieb., Nigella arvensis L., Nigella damascena L., Nigella elata Boiss., Nigella nigellastrum (L.) Willk., Nigella unguicularis (Lam.) Spenner, and Nigella lancifolia Hub.-Mor.) from Turkey have been investigated. The seeds contained 17.6–41.3% fixed oils. Linoleic (31.21–69.5%) and oleic acids (15.79–36.03%) were the major fatty acids in the oils. Eicosenoic acid was found in high amounts in the oils of N. nigellastrum and N. unguicularis seeds (23.12 and 17.47%, respectively). N. nigellastrum, N. elata and N. unguicularis seed oils showed the highest concentration of eicosadienoic acid (9.40, 8.39 and 7.17%, respectively). In all fixed oils, the quantities of unsaturated fatty acids were higher than those of the saturated analogues. |
