Nigella sativa L., Ranunculaceae, commonly named black cumin, is a spontaneous plant. Nigellae sativae semen has been used for a long time in the Arabian and Romanian ethnopharmacological field for its tonic effect. The scientific basis for using this plant was confirmed by phytochemical studies. These studies represent the scientifical confirmation of the empirical use of this vegetal product. The lipophylic fraction from Nigellae sativae semen contains, besides essential oils, fatty oils. The qualitative and quantitative analysis of fatty acids from mentioned oil were performed using GLC (Gas- Liquid Chromatography). The obtained fatty oil was found highly unsaturated, 84.35% from the total fatty acids representing the mono- and polyunsaturated fatty acids. The main fatty acid of the Tunisian Nigella sativa seeds was found the linoleic acid (C18:2) representing about 63.71% of the total fatty acids.
