In this study, it is aimed to determine the possibilities of cultivation of 2 taxa (Teucrium chamaedrys subsp. chamaedrys, Teucrium polium) belonging to the Lamiaceae family. The plants were collected from an area where plants grow naturally and cultivated in "Randomized Complete Block Design". Phenological observations, morphological measurements and plant elemental analysis were carried out in the natural and in the cultivated areas. 72 (96%) of Teucrium chamaedrys subsp. chamaedrys and 54 (72%) of Teucrium polium survived of the plants transferred to the cultivation area. Cultivated Teucrium chamaedrys subsp. chamaedrys showed higher growth compared to those in terms of plant width and number of spikes. Data on the morphological parameters of cultivated plants of T. polium was higher than that of. The highest N content for T. chamaedrys and T. polium was determined as (2.75, 2.09%) in the 2nd year cultivated plants. No statistical difference was observed in terms of other macro and micro elements in both plants of origin. [ABSTRACT FROM AUTHOR]

The genus Teucrium belongs to the Lamiaceae family. Lamiaceae is one of the important plant groups because most members of this group are used as medicinal and aromatic plants. In this study, the leaves and flowers of Teucrium chamaedrys subsp. chamaedrys and Teucrium polium, which were taken from both their natural habitat and cultivars, were analysed by SPME and GC-MS in two vegetation periods. The amount and the composition of volatile oil of cultivated plants were compared with plants from natural areas. Caryophyllene (12.20-23.74%) was the most abundant component in all samples of Teucrium chamaedrys except in samples from natural habitats of the first vegetation period. Moreover, 2-hexen-1-al (12.79-13.98%), germacrene-D (11.99-19.60%) and a-pinene (3.80-11.68%) were the dominant components of the T. chamaedrys, while in Teucrium polium samples, ß-myrcene (19.52-25.28%) was the common component in both sampling area of the first vegetation period, limonene (30.87-31.79%) had the highest amount in the second vegetation period. Besides, a-thujone (3.13-18.87%), a-pinene (0.94-17.93%) and germacrene-D (4.31-15.63%) were detected as major components in samples from both natural habitats and cultivars of T. polium.

Current study focused on two phases; in the first the composition and the amount of extractives were determined. Thus, hexane and acetone:water (95:5, v:v) extracts of Eucalyptus camaldulensis and Liquidamber orientalis bark were analysed by GC-MS to determine lipophilic and hydrophilic extractive composition of these species. The second phase was to identify anti-bacterial, anti-biofilm and anti-swarming effects of the gathered extractives. Total amount of lipophilic extractives was found 3.90 mg/g in E. camaldulensis whereas it was determined as 7.67 mg/g in L. orientalis bark. However, total amount of hydrophilic extractives in E. camaldulensis bark (55.51 mg/g) had almost 1.5 times more than L. orientalis bark (39.19 mg/g). Fatty acids and sugar groups were the dominant groups as lipophilic and hydrophilic, respectively, in both species. Anti-bacterial test was carried out by using three Gram-positive (Staphylococcus aureus, Methicillin Resistant Staphylococcus aureus, Bacillus cereus) and three Gram-negative (Pseudomonas aeruginosa, Escherichia coli and Pseudomonas aeruginosa PA01) strains with agar well diffusion method. In addition, the minimum inhibitory concentrations (MICs) of the extracts were also determined using the micro-dilution method. When hexane and acetone:water (95:5, v:v) extracts of E. camaldulensis and the acetone:water (95:5, v:v) extract of L. orientalis have anti-bacterial effect on Gram-positive bacteria but they do not have anti-bacterial effect on the tested Gram-negative bacteria. Whereas the hexane extract of L. orientalis did not show anti-bacterial activity on any tested strains. The minimum inhibitory concentration of these extracts ranged from 0.52 to 51.5 mg/ml. It was also found that hexane extract of E. camaldulensis inhibited biofilm formation and acetone extract of L. orientalis and E. camaldulensis indicated anti-swarming activity on P. aeruginosa PA01.

Extractives compose 5-10 % of wood by weight and they have important roles in trees. Extractive composition of different plant species has to be investigated in order to get the broadest sense. Thus, hexane and acetone:water (95:5, v:v) extracts of Arbutus andrachne and Platanus orientalis wood were analysed by GC-MS and GC-FID to determine lipophilic and hydrophilic extractive composition of these species. Total amount of lipophilic extractives was found 3,39 mg/g in A. andrachne wood, whereas it was determined as 16,91 mg/g in P. orientalis wood. However, total amount of hydrophilic extractives in A. andrachne had higher values. Fatty acids were detected as the dominant group in lipophilic extractives in both wood species. Acid 18:3 in A. andrachne wood (0,17 mg/g) and acid 16:0 in P. orientalis wood (0,19 mg/g) were determined as the highest fatty acids. [ABSTRACT FROM AUTHOR]

In this study, volatile components of C. orientalis subsp. orientalis and C. orientalis subsp. szovitsii which are belonging an important howthorn taxa for Turkey, was determined. Leaf and flower samples of plant taxa were collected from Muğla-Fethiye in 2012 and dried in room temperature for determining to volatile contents of howthorn taxa and these contents were determined by GC-MS As result of analyses, totally 53 volatile components belonging to C. orientalis subsp. orientalis and C. orientalis subsp. szovitsii taxa were determined. According to GC-MS results, most effective components were determined as 2-Hexenal (38,55%), 3-Hexenol (13,98%), Capronaldehyde (6,81%) for C. orientalis subsp. orientalis and Propyl methyl ketone (26.60%), Butyraldehyde(9,37%), 2-Hexenal (6,55%) in case C. orientalis subsp. szovitsii.
