Comparison of chemical composition and antibacterial activity of Nigella sativa seed essential oils obtained by different extraction methods
Original language description
Nigella sativa L. seed essential oils obtained by hydrodistillation (HD), dry steam distillation (SD), steam distillation of crude oils obtained by solvent extraction (SE-SD), and supercritical fluid extraction (SFE-SD) were tested for their antibacterial activities, using the broth microdilution method and subsequently analyzed by gas chromatography and gas chromatography-mass spectrometry. The oils obtained by HD and SD were dominated by p-cymene, whereas the major constituent identified in volatile fractions obtained by SD of extracted oils was thymoquinone. All oil samples were significantly more active against gram-positive than against gram-negative bacteria.

Srovnání chemického složení a antibakteriální aktivity silice ze semen Nigella sativa, získané různými extrakčními metodami
Czech description
Silice ze semen Nigella sativa, získané hydrodestilací (HD), destilací semen s vodní parou (SD), destilací extraktu semen s vodní parou (SE-SD) a superkritickou extrakcí (SFE) byly testovány na antibakteriální aktivitu s použitím mikrodiluční metody. Získané silice byly též analyzovány pomocí GC-MS. V silicích získaných metodami HD a SD dominoval p-cymen, zatímco v ostatních vzorcích převažoval thymohydrochinon. Všechny silice byly aktivnější na grampozitivní bakterie ve srovnání s gramnegativními.
