Öğe Composition and Anticandidial Activity of the Essential Oil of Kundmannia syriaca from Turkey(Springer, 2016) Kaya, Ayla; Demirci, Betul; Dinc, Muhittin; Dogu, Suleyman[Abstract Not Availabe]Öğe Composition of the essential oil of Stachys sericantha, S-gaziantepensis, and S-mardinensis (Lamiaceae) from Turkey(Taylor & Francis Inc, 2017) Kaya, Ayla; Demirci, Betul; Dogu, Suleyman; Dinc, MuhittinThe genus Stachys L. one of the largest genera of Lamiaceae and Stachys species are used by many people for the therapeutic value of their essential oils. In this study, water-distilled essential oil of three species of Stachys was analysed. The analysis was performed by using gas chromatography-flame ionisation detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) systems simultaneously. The major components found were hexadecanoic acid (23.7%), dodecanoic acid (11.3%), and caryophyllene oxide (10.7%) for S. sericantha P.H. Davis (endemic); -pinene (53%), -pinene (8.2%) for S. gaziantepensis M. Dinc and S. Dou (endemic); Menthyl acetate (15.3%), isomenthone (15.0%), pulegone (10%), spathulenol (7.0%), and caryophyllene oxide (6.7%) for S. mardinensis (Post) R. Mill.Öğe Compositions of essential oils of Salvia adenophylla, Salvia pilifera, and Salvia viscosa in Turkey(Taylor & Francis Inc, 2017) Kaya, Ayla; Dinc, Muhittin; Dogu, Suleyman; Demirci, BetulIn the Anatolia folk medicine, Salvia species are used by many people in various villages and towns for the therapeutic value of their essential oils. In this study, water-distilled essential oil of three species of Salvia (Lamiaceae) was analyzed. The analysis was performed using a gas chromatography (GC-FID) and gas chromatography-mass spectrometry systems, simultaneously. The major components were found as -pinene (16.2%) and -pinene (14.4%) for Salvia adenophylla Hedge & Hub-Mor. (endemic); -pinene (24.9%), myrcene (9.0%), and -humulene (7.9%) for Salvia pilifera Montbret et Aucher ex Bentham (endemic); -copaene (13.0%), -caryophyllene (10.8%), -muurolene (9.8%), -cadinene, and caryophyllene oxide (8.0%) for Salvia viscosa Jacq.Öğe Compositions of the Essential Oils of Teucrium cavernarum and Teucrium paederotoides, Two Endemic Species from Turkey(Taylor & Francis Ltd, 2013) Kaya, Ayla; Demirci, Betul; Dinc, Muhittin; Dogu, Suleyman; Husnu Can Baser, K.The essential oils from aerial parts of Teucrium cavernarum P. H. Davis and Teucrium paederotoides Boiss. & Hausskn. (Lamiaceae) both of which are endemic species in Turkey were isolated by steam distillation and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Plants were collected during the flowering period from Karaman (T. cavernarum) and Gaziantep (T. paederotoides) province of Turkey. Thirty compounds were identified in the oil of T. cavernarum and seventy three compounds were identified in the oil of T. paederotoides. The major components were characterized as beta-caryophyllene (32.9 %), germacrene D (20.7 %), caryophyllene oxide (14.1 %) and bicyclogermacrene (6.3 %) for T. cavernarum and germacrene-D (20.8 %), pulegone (9.5 %), bicyclogermacrene (9.2 %), hexacecanoic acid (7.9 %) and spathulenol (6.5 %) for T. paederotoides, respectively.Öğe Taxonomic status of the subspecies of Teucrium lamiifolium in Turkey: reevaluation based on macro- and micro-morphology, anatomy and chemistry(Wiley, 2013) Dogu, Suleyman; Dinc, Muhittin; Kaya, Ayla; Demirci, BetulTeucrium stachyophyllum P. H. Davis was first described as a separate species in the Syrian, Lebanon and Palestine Flora', but was reduced to a subspecies of T. lamiifolium d'Urv. in the Turkish Flora'. Studies on the macro- and micro-morphology as well as the anatomy of populations of T. lamiifolium subsp. stachyophyllum (P. H. Davis) Hedge & Ekim and T. lamiifolium subsp. lamiifolium in Turkey have been carried out based on herbarium specimens and field observations. The results from the anatomical studies on stems and leaves show that although the two taxa are similar in stem anatomy, they differ in terms of mesophyll thickness and occurrence of crystals in the upper epidermal cells of the leaf. Light and scanning electron microscope analyzes revealed striking differences in colour, size, sculpture and gland density between nutlets of the two taxa. Morphological studies also showed that there were important differences between the two taxa in terms of inflorescence, indumentum, and stem length and thickness. In addition, the essential oils from aerial parts of T. lamiifolium subsp. stachyophyllum and T. lamiifolium subsp. lamiifolium were isolated by steam distillation and analysed by gas chromatography (GC) and gas chromatographymass spectrometry (GCMS). The major components were characterized as -caryophyllene (23.544.8%), trans--bergamotene (22.426.4%), germacrene D (22.2%) and (Z)--farnesene (14.0%) for subp. lamiifolium and trans--bergamotene (38.141.1%) and -caryophyllene (8.78.9%) for subsp. stachyophyllum, respectively. As a result of the studies, it is proposed that the taxon treated as T. lamiifolium subsp. stachyophyllum in the Turkish flora should be raised to specific rank as T. stachyophyllum.
