Fig. 2. Concentration of γ-terpinene and thymoquinone in the essential oils of tissues and seed developmental stages in N. sativa. The authenticity of metabolites was confirmed by comparing their retention time and mass spectra to those of authentic standards. Bars represent means (n = 3) ± S.E. Bars with different letters are significantly (P <0.05) different according to Duncan's test.
