“…In T. polium, the composition of the essential oil is varied according to region. In previous studies and a preliminary work conducted in our lab, β-caryophyllene was found as a component of the essential oil of T. polium in most regions studied (Hassan et al 1979;Rizk et al 1986;Cakir et al 1998;Eikani et al 1999;Aburjai et al 2006;Kabouche et al 2007). Therefore, it was used as a standard to study the essential oil in the current study.…”

“…Essential oil studies on T. polium collected from different geographical regions revealed that β-caryophyllene was found in multiple analyses (Hassan et al 1979;Rizk et al 1986;Cakir et al 1998;Eikani et al 1999;Aburjai et al 2006;Kabouche et al 2007). The sesquiterpene β-caryophyllene is a major plant volatile found in large amounts in the essential oils of many different spice and food plants, such as oregano (Origanum vulgare L.), cinnamon (Cinnamomum spp.…”

“…Different chemical compounds have been isolated and identified from T. polium worldwide, principally: tridoids and flavonoids (Rizk et al 1986), neo-clerodanediterpenoids (Alcazar et al 1992;Bedir et al 1999), abietane diterpenoids (Cuadrado et al 1992), and furanoidditerpenes (Malakov and Papanov 1983). Utilizing gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS) analysis, several research groups have evaluated the essential oil of T. polium grown in different geographic areas and revealed the presence of several compounds varying in their major constituent(s) and their concentration depending on the geographic origin (Hassan et al 1979;Rizk et al 1986;Cakir et al 1998;Eikani et al 1999;Aburjai et al 2006;Kabouche et al 2007).…”

Thymus genus (Lamiaceae) has been found to possess significant biological activities, including antimicrobial, antioxidant, spasmolytic, antitussive, bronchiolitis, antifungal, sedative, and rubefaciant [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Twelve species are distributed in Algeria [7], nine of them endemic. In continuation of our works on Lamiaceae essential oils [8][9][10][11], we present here the essential oil composition and the antioxidant activity of the endemic species Thymus dreatensis Batt.Extraction. The hydrodistillation in a Clenvenger-type apparatus of the aerial parts of Thymus dreatensis yielded 2.1% of a pale yellowish oil.GC Analysis. GC analysis was performed on a Hewlett Packard 6890 gas chromatograph equipped with an FID and HP-5MS capillary column (bonded and cross-linked 5% phenylmethylpolysiloxane 30 m u 0.25 mm, film thickness 0.25 Pm). Operating conditions were as follows: carrier gas He with a flow rate of 2 mL/min; column temperature 60-275qC at a rate of 4qC/min; injector temperature 280qC; injected volume 0.1 mL of the oil; split ratio 1:50.GC/MS Analysis. The oil was analyzed by GC/MS using a Hewlett Packard 6890 mass selective detector coupled with a Hewlett Packard 6890 gas chromatograph, equipped with a FID and HP-5MS capillary column (bonded and cross-linked 5% phenylmethylpolysiloxane 30 m u 0.25 mm, film thickness 0.25 Pm), under the same conditions as GC (column, oven temperature, flow rate of carrier gas). The MS operating parameters were as follows: ionization potential 70 eV; ion source temperature 200qC; resolution 1000.Identification of Components. Essential oil components were identified based on their retention indices (determined with reference to a homologous series of normal alkanes) and by comparison of their mass spectral fragmentation patterns with those reported in the literature [12,13] and with authentic compounds.Thirty-five components were identified, representing 97.4% of the total oil. The major constituents of the oil were thymol (28.1%), J-terpinene (18.7%), thymyl methyl ether (10.9%), p-cymene (8.8%), and linalool (5.0%). Compared with our previously reported essential oils of T. ciliatus, T. fontanesii, and Thymus numidicus [1, 14-16] which were high-thymol chemotypes, it seems that the composition of the present essential oil is different. Nevertheless, J-terpinene was also mainly found in T. fontanesii oil (15.9%) [14] (Table 1).Antioxidant Activity. The antioxidant activity was evaluated using the E-carotene-linoleic acid test system [17,18]. E-Carotene (0.5 mg) in 1 mL chloroform was added to 25 PL of linoleic acid and 200 mg of Tween 40 emulsifier mixture. After evaporation of chloroform under vacuum, 100 mL distilled water saturated with oxygen was added, followed by vigorous shaking. Then 4.0 mL of this mixture was transferred into different tubes containing different concentrations of the sample. As soon as the emulsion was added to each tube, the zero time absorbance was measured at 470 nm using a spectrophotometer. The emul...

The hydrodistilled essential oils obtained from aerial flowering parts of Teucrium stocksianum ssp. stocksianum (TSS) and T. stocksianum ssp. gabrielae (TSG) from Iran were analyzed by capillary GC and GC/MS. The oil analysis of two subspecies led to the identification of 65 compounds that accounted for 93.3 and 95.1% of the total oil compositions, respectively. Sesquiterpenoids (52.9%) constituted the main compounds in the essential oil of TSS represented mainly by cis-sesquisabinene hydrate (12.0%), followed by epi-β-bisabolol (6.6%), guaiol (5.4%), and β-eudesmol (4.4%), whilst monoterpenoids (61.2%) were found to be the major components of the oil of TSG, represented by α-pinene (23.0%), β-pinene (13.0%), myrcene (6.3%), and sabinene (6.3%). The principal component in both subspecies, TSS and TSG, was α-pinene (22.0 and 23.0%, resp.) and β-pinene (6.5 and 13.0%, resp.). epi-α-Cadinol, myrcene, and sabinene, which were detected as principal compounds of TSG, were characterized in lower amounts (<1.5%) in the oil of TSS. Seven components were identified in the oil of TSS corresponding to 25.9% of total oil, which were totally absent in the oil of TSG, of which cis-sesquisabinene hydrate (12.0%), guaiol (5.4%), and β-eudesmol (4.4%) were in considerable amounts. Taxonomic position of the subspecies is discussed on the basis of phytochemical data.
