However, there is no description of the effect of EOLs thymol, p-cymene
, myrcene and caryophyllene on sciatic nerve excitability, which was demonstrated by other terpenes and terpenoids.
In trial 1, the effects of 11 ACEO (eugenol [99% purity], carvacrol [98% purity], citral [95% purity], limonene [96% purity], 1,4-cineole [85% purity], [gamma]-terpinene [97% purity], p-cymene
[99% purity], linalool [97% purity], bornyl acetate [95% purity], [alpha]-pinene [98% purity], and [beta]-pinene [99% purity]), which were provided by Sigma-Aldrich Chemical (Sigma-Aldrich, St.
copticum essential oil containing main constituents carvacrol followed by p-cymene
, T-terpinene and apiol has shown overall 50% sensitivity greater than pure essential oil.
Blends were also prepared with p-xylene (20 vol%) and p-cymene
(20 vol%) to demonstrate the impacts of increasing aromatic content without fuel oxygen.
To determine the cytotoxicity of ethanolic extracts and their individual components, cells were treated with the different treatments (thymol, carvacrol, p-cymene
, and/or 1-octacosanol dissolved in 1% ethanol [the vehicle solution had no effect on the antioxidant and cytotoxic activities of the extract and/or its constituents]) in media.
essential oil were cyclohepta-1,3,5,-triene, 2H-1,4-pyridoxazin-3(4H)-one, L-carvenol, p-cymene
, a- terpineol, b-sitosterol, tyranton, mesityl oxide, - terpinene and b-linalool, which have the high potentiality against isolated Xanthomonas sp.
In conclusion, our finding showed that thymol, p-cymene
and c-terpinene the main compounds of Z.
Quantization of major constituents of the oils were compared by the retention time and RIs of related authentic components (thymol, carvacrol, p-cymene
, [gamma]-terpinene) (Adams 2001; National Institute of Standard and Technology 1998).
Some constituents such as p-cymene
, 1,8 cineol, [gamma]-terpinene and linalool were found in the essential oil only of the flower and leaf, but absent in the rhizome.
The monoterpenes ate represented mainly by monocyelic compounds of the p-cymene
group, such as limonene, terpinene, phellandrenes and the oxide 1,8-cineole.
Fate of the dietary terpene, p-cymene
, in the male koala.
Phenols and gamma-terpinene were found to possess excellent antioxidant activity whereas cuminal, cuminyl alcohol and p-cymene
showed weak activity.
The monoterpene: ([+ or -])-[beta]-citronellol, ([+ or -])-citronellal, (-)-[alpha]-pinene, (-)-[beta]-pinene, [alpha]-terpinene, [gamma]-terpinene, [alpha]-terpineol, 1,8-cineole, citral, thymol, carvacrol, [alpha]+[beta]-thujone, camphene, ([+ or -])-camphor, (-)-borneol, p-cymene
, myrcene, menthone, ([+ or -])menthol, geraniol, geranyl acetate, linalool, linalyl acetate, (R)-(-)-[alpha]-phellandrene, estragole, (R)-(-)-carvon, limonene showed potent phytotoxic activity and these compounds could be used both as potential bio-herbicides and lead structures for the development of new, potentially safe and ecocompatible pesticides (Martino et al.
The main components were y-terpinene, myristicin, thymol, p-cymene
and carvacrol .
The major components in straw like, limonene and decanal was higher under Giza condition and vice linalool, [gamma]-terpinene and p-cymene
which were higher under North Sinai condition.
