TL;DR: The seed oils of three accessions of Nigella sativa and N. damascena, sown on different dates, were obtained by Likens-Nickerson hydrodistillation and analyzed by GC/MS to characterize the main components of N. sativa oil.
Abstract: The seed oils of three accessions of Nigella sativa and N. damascena, sown on different dates, were obtained by Likens-Nickerson hydrodistillation and analyzed by GC/MS. The main components of N. sativa oil were p-cymene (33.8 %) and thymol (26.8 %), with only small amounts of thymoquinone (3.8 %). N. damascena oil was characterized by almost 100% sesquiterpenes, of which β-elemene (73.2 %) represented about three-quarters of the total amount.

TL;DR: The volatile components in chloroform extracts and essential oils from the seeds of Nigella damascena and Nigella sativa were analyzed by GC and GC/MS.
Abstract: The volatile components in chloroform extracts and essential oils from the seeds of Nigella damascena and Nigella sativa were analyzed by GC and GC/MS. The volatile compositions differed in the two species: N. damascena contained sesquiterpenes, including a large proportion of β-elemene (27.7% extract, 54.7% oil) and methyl 3-methoxy-N-methyl anthranilate (30.7% extract, 12.7% oil), which account for the characteristic aroma of this species, whereas only monoterpenes, including p-cymene (49.0% extract, 47.4% oil) and thymoquinone (20.6% extract, 20.8% oil), were detected in N. sativa.

TL;DR: Antimicrobial tests showed the essential oil to be active only against Gram positive bacteria; among the extracts, the BuOH was active against Pseudomonas aeruginosa and Staphylococcus aureus.
Abstract: The essential oil, various extracts at different polarity, fractions, and pure compounds obtained from Nigella damascena plants and seeds were screened for biological activity. Antimicrobial tests showed the essential oil to be active only against Gram positive bacteria; among the extracts, the BuOH was active against Pseudomonas aeruginosa and Staphylococcus aureus. Molluscicidal activity was absent.
