Chemical Composition and Antifungal Activity of Nigella Sativa L . Oil Seed Cultivated In Morocco

Nigella sativa L. commonly called black seed belongs to the family Ranunculaceae is known for its indigenous medicinal uses since immemorial time. The present study was carried out in order to characterize the Nigella seed oil cultivated in Morocco for its fatty acid and sterol composition using gas chromatography. The results indicated the presence of linoleic acid (58.5%) and oleic acid (23.7%) as unsaturated fatty acids and palmitic acid (13.1%) as saturated fatty acid while β-sitosterol and stigmasterol were among the major components, together constituting about 69 % of total sterols. Nigella seed oil has a strong antifungal activity compared to the conventional fungicides. Our findings demonstrate that Nigella seed oil has an antifungal activity that might be a natural potential source of antifungal used in food, in cosmetics and in pharmaceuticals products.
