The main components of the essential oil from the flower were germacrene-D (21.2%), p-cymene (20.6%), bicyclogermacrene (17.6%), [gamma]-dodecadienolactone (13.7%), and terpinolene (9.4%).
As an introduction to this discussion, consider the following from the Farkhondeh et al paper: "The black cumin oil consists of main medicinal components such as tocopherols, phytosterols, polyunsaturated fatty acids, thymoquinone (TQ), p-cymene, carvacrol, t-anethole, and 4-terpineol.
Following carvacrol, the compounds that presented the highest content in most plants were [gamma]-terpinene, p-cymene and methyl-ether-thymol.
The result revealed that the major essential oils from turmeric rhizomes are Eucalyptol (76.46%), [alpha]-Terpinene (4.41%), [gamma]-Terpinene (3.32%), p-Cymene (1.31%), and [alpha]-Terpineol (0.62%) while [alpha]- Zingiberene (17.43%), [beta]-Sesquiphellandrene (3.10%), Eucalyptol (2.75%), Furfaral (1.76%), [alpha]-Terpineol (1.35%), endo-Borneol (1.31%), Limonene (1.21%), Thunbergol (0.84%), Citral (0.56%), Oxirane (0.45%), Caryophyllene oxide (0.42%), Nerolidol (0.31%), exo-Norborneol (0.27%), cis-Verbenol (0.12%), Linaloloxide (0.06%), and Squalene (0.02%) are the major essential oil compounds detected in ginger rhizomes.
From the Satureja hortensis essential oil, 20 compounds were separated by GC-MS, three of them being in a majority rate: carvacrol (19.68%), o-cymene (30.86%), and p-cymene (28.07%), except [alpha]-pinene (2.608%), 1.3-octadiene (1.563%), [beta]-pinene (2.238%), m-cymene (5.989%), (R)-isocarvestrene (1.142%), [gamma]-terpinene (1.285%), and 3-carene (1.457%) proportion of other components being below 1%.
The main constituents of EOLs are the monoterpenoids thymol, p-cymene and myrcene, and the sesquiterpene caryophyllene (1).
Furthermore, [alpha] terpineol, [beta]-pinene, and p-cymene are only present in our sample and that of Saudi Arabia.
We identified 19 compounds in the n-hexane juice extract, including limonene, [gamma]-terpinene, myrcene, [alpha]-pinene, [beta]-pinene, [beta]-phellandrene, p-cymene, and [alpha]-terpinolene (Table 2).
Thus, the predominant presence of monoterpenes ([alpha]-pinene, p-cymene, [alpha]-phellandrene, limonene, and [beta]-pinene) in the fraction of nebulized and inhaled air of Formulations B, D, and E (Table 2) may be related to the antinociceptive activity.
