This is followed by two-four layers of parenchymatous cells and finally, a sepia-pigmented layer containing thick-walled rectangular lengthened cells. Endosperm comprises narrow rectangular cells mostly composed of oil spheres. The chemical composition of the plant is illustrated in Fig . Thymoquinone with a chemical name of 2-isopropyl-5-methylbenzo-1, 4quinone has been identified as a phytochemical complex found excessively in N. sativa seeds and oil. It was first identified and extracted by El-Dakhakhny by performing thin-layer chromatography on a silicacoated TLC plate.('Thymoquinone and its therapeutic potentials', 2015) Thymoquinone has great potential as an anti-oxidant, anti-bacterial, antifungal and anti-inflammatory compound. The active compounds found in these seeds are thymoquinone, thymohydroquinone, dithymoquinone (nigellone), thymol, carvacrol, nigellicine, nigellidine and α-hedrin. Thymoquinone exists in a tautomeric form and there is a presence of a keto group in high concentration due to which there are effects of pharmacological activity in them. It is a natural compound and has received high amounts of interest and focus due to its therapeutic properties.('Thymoquinone: Potential cure for inflammatory disorders and cancer', 2012). However, thymoquinone as a separate biomolecule is unstable due to its poor water solubility, leading to low absorptivity and bioavailability. Therefore, it has to be dissolved in a suitable solvent like DMSO without altering its capability. The pharmacological activity of Thymoquinone has been illustrated in Fig .
