9%) were the main components of oil, followed by p-cymene
Furthermore, the significance of the phenolic ring was demonstrated by the lack of activity of the monoterpene cyclic hydrocarbon p-cymene
Moreover, the plants treated with salicylic acid led to increase in cumin aldehyde and [beta]-terpinene, p-cymene
In the present work, we used p-cymene
/[beta]-cyclodextrin ([beta]-CD) complex and p-cymene
isolated to evaluate in nociceptive and inflammatory animal protocols, and study whether the complex formulation is able to improve the pharmacological activity of this monoterpene.
On the other hand, its constituents thymol, p-cymene
, [gamma]-terpinene and myrcene are considered weak cytotoxic agents.
Tween 80, Indomethacin, [lambda]-Carrageenan, p-Cymene
(99% purity) and [beta]-cyclodextrin ([greater than or equal to] 97% purity) were purchased from Sigma-Aldrich (USA).
In contrast, the highest [gamma]-terpinene and p-cymene
contents as precursors of carvacrol and thymol were observed in post-flowering and full-flowering and and the lowest in pre-flowering stage, but not significant differences are there in the total amount of the main components in different ontogenesis condition (Table, 3).
Deuterium/hydrogen ratio analysis of thymol, carvacrol, [gamma]-terpinene and p-cymene
in thyme, savory and oregano essential oils by gas chromatography-pyrolysis-isotope ratio mass spectrometry.
This study shows that the Origanum majorana, is the main source for trans sabinene hydrate, Terpinene-4-ol and other valuable components such as [delta]-terpinene, p-cymene
, sabinene, [alpha]-terpineol, [alpha]-phellandrene, and [beta]-caryophyllene.

They determined that essential oil content were between 4,8-10,8 % and major components were carvacrol (481,9- 489,9 mg/mL), [gamma]-terpinene (40,7- 65,2 mg/mL), p-cymene
(40,2- 54,0 mg/mL) from June to July.
Standard thymol pure sample was supplied by Merk and the standard carvacrol and P-cymene
pure samples were supplied by Aldrich.
