“…The compounds reported from the essential oil of T. transcaspicus aerial parts collected in Mashhad province during the flowering stage were thymol (56.41%), terpinene (7.74%), carvacrol (7.62%), -cymene (6.34%), and thymol methyl ether (4.69%) [35]. Unlike our study, Sefidkon et al (1999) identified thymol, carvacrol, -terpinene, and -cymene from the essential oil of T. kotschyanus aerial parts in different stages of growth by different methods from Tehran [36]. Such differences are due to the differences in geographical regions and climate conditions, plant collection area and time, developmental stage and plant growth conditions (light, water, mineral, and organic matter), and extract methods of essential oil.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…p-Cymene and γ-terpinene steadily increased from spring to summer, when they reached the maximum level, and then from summer to autumn their levels showed a gradual decrease. These trends parallel those observed for O. onites from Turkey [12] and Thymus kotschyanus from Iran [13]. It has been previously noted that essential oil yields and quality are highest during the full flowering stage [14].…”

“…The presence of thymol and carvacrol, as well as their precursor pcymene in the oil was expected, although the absence of linalool was noteworthy. These four components have been previously found as constituents of most Thymus oils (Mc Gimpsey et al, 1994;Stahl-Biskup et al, 1991;Sefidkon et al, 1999). A comparison of the results obtained in this study with previously reported data of the Thymus species oils from different countries, showed that the predominance of thymol, carvacrol, p-cymene and 1, 8-cineole as main components (Sefidkon and Askari, 2002).…”
