“…The seed and its oils were found to exhibit several pharmacological properties among them, anticancer, antiviral, antibacterial, antipyretic, galactagogue, carminative, antidiabetic, and antioxidant activities (Abdelfadil et al, 2013;Darakhshan, Pour, et al, 2015;Darakhshan, Tahvilian, et al, 2015;Salem, 2005;Salomi et al, 1992). Most of these biological activities were mainly associated with thymoquinone, which is the major component of the oil, in addition to polyunsaturated fatty acids, phenols, quinone, carvacrol and 4-terpineol (A.…”

Nigella sativa L. seeds are widely used in Sudan as a spice, food preservative, and medicine. Sudan does not grow the plant. The study aimed to compare the chemical profile and antibacterial activity of fixed and essential oils of N. sativa from Ethiopian and Indian seeds and the oil offered by Attarin in the local market. A Soxhlet device extracted fixed oils and hydrodistillation to obtain essential oils and analysed their oil profile using GC-MS. Disk diffusion was used to test antimicrobial activity. The fixed oil of Ethiopian (EFO) and Indian (IFO) seeds contained ten components, with linoleic acid (50.12% in EFO and 57.69% in IFO) being the most abundant. Ethiopian seeds were used to extract the essential oil. 51.96% of the oil was hydrogenated monoterpenes. The main chemicals were p-cymene (36.76%) and thymoquinone (18.70%). There were fixed and essential oils in the Attarin oil sample. The main component was linoleic acid (14.61%), followed by p-cymene (13.85%). The maximum antibacterial activity (MIC 6.25 µg/disc) was seen in both fixed and liquid oil samples against Escherichia coli and Pseudomonas aeruginosa. The best anti-P. aeruginosa action was attarin oil (MIC 12.5 µg/disc). Finally, the Sudanese market needs to standardise N. sativa seeds and oil.

The current study aimed to assess the impacts of fertilization and plant density on fixed oil content, oil yield, and fatty acids profile of Nigella sativa L. under Mediterranean environment. The 3-year experiment was set up in a split-plot design with three replications, two main plots (plant densities: 200 and 300 plants m-2) and four sub-plots (fertilization treatments: control, seaweed compost, farmyard manure and inorganic fertilizer). The seed yield, fixed oil content, as well as the fixed oil yield were positively affected by the increase of available nitrogen and negatively by the increase of plant density, with their highest values recorded in the low-density and inorganic fertilization. Regarding the composition in fatty acids, it was found that with the increase of plant density there was a decrease in saturated (SAFA: myristic, palmitic and stearic acid) and polyunsaturated (PUFA: linoleic, α-linolenic and eicosadenoic acid) fatty acids, while there was an increase in oleic acid which was the only monounsaturated fatty acid detected in fixed oil. In terms of fertilization, the organic fertilizers were the ones that contributed positively to the content of the respective fatty acid. As a conclusion, plant densities greater than 200 plants m-2 result in lower seed yield, fixed oil content and yield, whereas the effect of inorganic fertilization was equally important in seed and fixed oil yield; however, when the seed and/or its fixed oil are utilized for their high medicinal and nutritional value, the application of compost is indicated, resulting in a significant increase in the content of PUFAs, characterized for their beneficial effects on human health.
