Essential Oils of Nigella sativa L. and Nigella damascena L. Seed
TLDR
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.read more
