The essential oils of three wild-growing Thymus species, collected from west of Iran during the flowering stage, were obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). Under the optimum extraction and analysis conditions, 44, 38, and 38 constituents (mainly monoterpenes compounds) were identified in T. kotschyanus Boiss. and Hohen, T. eriocalyx (Ronniger) Jalas, and T. daenensis subsp lancifolius (Celak) Jalas which represented 89.9%, 99.7%, and 95.8% of the oils, respectively. The main constituents were thymol (16.4-42.6%), carvacrol (7.6-52.3%), and γ-terpinene (3-11.4%). Antioxidant activity was employed by two complementary test systems, namely, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging and β-carotene/linoleic acid systems. Antioxidant activity of polar subfraction of T. daenensis subsp lancifolius (Celak) Jalas was found to be higher than those of the others in DPPH assay, while nonpolar subfraction of T. eriocalyx (Ronniger) Jalas has most antioxidant activity in β-carotene/linoleic acid test (19.1 ± 0.1 μg/mL and 96.1 ± 0.8% inhibition rate, resp.).

“…glabrescens known as a member of thyme species is used as traditional medicine among people. The chemical composition of TE reveal that carvacrol represent the most important compounds in the oil, that is found as 44.2% by Meriçli (1986) and, as 53-70% by Başer (2002). This extract also contains p-cymene (7%), c-terpinene (6%) and thymol (6%) (Başer 1993).…”

Effects of Thymus kotschyanus var. glabrescens Boiss. extract on mitomycin-C induced chromosomal aberrations and sister chromatid exchanges in human lymphocytes

et al. 2006

In this investigation, clastogenic effects of Thymus kotschyanus var. glabrescens Boiss. extract (TE) and anticlastogenic effects of this extract against Mitomycin C (MMC) induced chromosome damage have been evaluated in human peripheral blood lymphocytes in vitro. Two series of experiments were conducted. In the first, only 10 -5 , 10 -4 , 10 -3 and 10 -2 ll ml -1 concentrations of TE were used for 48 h to detect potential clastogenicity. In the second, MMC (0.38 lg ml -1 ) plus 10 -5 , 10 -4 , 10 -3 and 10 -2 ll ml -1 concentrations of TE were used for 48 h to determine anticlastogenic effects. TE did not increase sister chromatid exchanges (SCEs) (except 10 -2 ll ml concentration) and chromosome aberrations (CAs) significantly compared with negative and solvent controls. However, it decreased the frequency of MMC induced chromosome aberrations. Decreasing was significant at 10 -4 , 10 -3 and 10 -2 ll ml -1 concentrations. On the other hand, TE significantly increased MMC-induced SCEs for all treatment groups compared with positive control.
