“…The oil yield decreased towards the stage of seed maturity. Similar results reported by Omidbaigi et al (2009), who . Comparison of the mass spectrum (A) of obtained from peak 13 in Fig 1, (B) terpinolene spectrum obtained from mass spectral library with the resolved spectra GC-MS analysis of which gave rise to four major signal at m/z 121, 136,93,43, also almost the same fragmentations as those of terpinolene were observed ( Fig.…”

“…Moreover, the highest level of borneol and bornyl acetate was obtained at the post-flowering stage (Table 1). Omidbaigi et al, (2009) determined that geraniol was the major component (54.2-72.5%) in Thymus × citriodorus and obtained the highest geraniol content (72.5%) in the essential oil at the pre-flowering stage and the lowest geraniol content (54.2%) at the fruit development stage. Stahl-Biskup and Holthuijzen (1995) reported that geraniol was the main compound (more than 60%) and also detected geranyl acetate (1.0%), geranyl butyrate (0.8%), nerol (2.8%), and citronellol (0.3%) in Thymus × citriodorus.…”

“…Plant ontogeny is also one of the most important factors affecting essential oil accumulation in essential oil plants (Sangwan et al, 2001). Omidbaigi et al (2009) reported that the most suitable time for harvesting of lemon thyme (Thymus × citriodorus) to obtain high essential oil production was at fruit set stage. However, harvesting time should be recommended according to its location and environmental conditions (Badi et al, 2004).…”

Thymus is represented by 39 species (60 taxa) in Turkey and the rate of its endemism is 45% in Turkey. The herb is widely used for several purposes. Its essential oil compositions and biologically active substances are affected by the phenological stages. Therefore, the aim of this study is to evaluate the variations in the essential oil composition of Thymus × citriodorus (Pers.) Schreb. growing in Southeastern Anatolia Region of Turkey at different phenological stages (pre-flowering, full flowering, post flowering). The oils were obtained by hydrodistillation of air-dried samples. The yields of oils (w/w %) at different phenological stages was respectively 2.0% at pre-flowering state, 1.9% at flowering stage, and 1.3% at post-flowering stage. T. × citriodorus was determined mainly by using GC/MS. A total of 21 compounds, representing 93.9% in the preflowering stage, 98.8% in the flowering stage and 98.91% in post-flowering of the total oil, were identified. Monoterpene hydrocarbons (terpinolene) and oxygenated monoterpenes (α-terpineol) were observed to have the highest percentage in T. × citriodorus oil. The major compounds of the oil were terpinolene, α-terpineol, linalool, bornyl acetate and borneol. The highest percentage of terpinolene was determined to be 71% in flowering stages.

“…The major constituents included transgeraniol (30.07%), trans-citral (15.06%), cis-citral (11.71%), and cis-geraniol (7.65%) ( Table 3). Omidbaigi et al (2009) studied the effect of various harvest times on the quality and quantity of lemon thyme essential oil and showed that the highest oil yield (2.21%) was obtained at the beginning of flowering, with geraniol being the predominant (54.2-72.5%) component. The highest geraniol content (72.5%) in the essential oil was measured before the flowering stage and the lowest content (54.2 %) was measured at the fruit-set stage.…”

Lemon verbena (Lippia citriodora H.B.K., Verbenaceae family) is indigenous to South America and cultivated as an aromatic plant in various parts of world. Lemon thyme (Thymus citriodorus L.), Lamiaceae family, is a perennial medicinal plant native to southern Europe and is cultivated in the Mediterranean region. These species are cultivated mainly for the lemon-like aroma emitted from their leaves due to the presence of dimethyl-2,6- octadienal, also known as lemonal or citral, which is used in food and perfumery for its citrus effect. The aim of this study was to determine the mineral content and essential oil components of L. citriodora and T. citriodorus plants grown under semi-arid climatic conditions in Turkey. The aerial parts of lemon thyme and lemon verbena plants were extracted using hydrodistillation. The essential oil composition was analyzed by gas chromatography-mass spectrometry (GC-MS) and the microelement contents of the herbs were examined via inductively coupled plasmaoptical emission spectrometry (ICP-OES). The microelement contents were 0.249, 1.630, 16.41, 0.106, and 13.1-36.2 mg kg-1 for cadmium (Cd), copper (Cu), iron (Fe), and manganese (Mn), respectively, in lemon thyme, and 0.275, 4.584, 248.1, 15.71, and 1.803 mg kg-1 for Cd, Cu, Fe, Mn, and zinc (Zn), respectively, in lemon verbena. Fifty compounds were identified in lemon verbena essential oil, including limonene (30.33%), trans-citral (17%), cis-citral (12.77%), caryophyllene oxide (5.71%), and geraniol acetate (4.02%) that together constituted 99.86% of the oil composition. We also identified 22 compounds constituting approximately 85.11% of lemon thyme essential oil, including transgeraniol (30.07%), trans-citral (15.06%), cis-citral (11.71%), cis-geraniol (7.65%), and 3-octanol (6.18%).

“…A Thymus x citriodorus-ból a geraniolt a virágzás előtti fázisban mutatták ki legnagyobb százalékban, míg a terméses állapotban lecsökkent a geraniol aránya. A geraniál aránya ellentétesen változott (Omidbaigi et al, 2009). A Thymus hyemalis és a Th.…”
