Volatile Constituents of Taxus baccata L. Leaves from Western and Southern Turkey

Abstract

The genus Taxus L. is classified in the family of Taxaceae and represented by eight species 1,2 . Taxus (yew) species range from North America into Central America and from Eurasia to Southeast Asia 3 . Only one species of Taxus is growing in Turkey, which is Taxus baccata L., a toxic plant and called European yew 4 .Volatile compounds were extracted from T. baccata L. leaves collected from northern Turkey (Black sea region) have been studied by Erdemoglu et al. 5 . However, the geographical place of growth of the plant influences chemical composition of the volatile oil 6 . Therefore, the essential oils of T. baccata L. leaves collected from western (Aegean region) and southern (Mediterranean region) Turkey were analyzed by gas chromatographic method using flame ionization and mass selective detections in this study. EXPERIMENTALThe leaves of T. baccata L. were collected from Bozdag-Acipayam/Denizli in Aegean region of Turkey at an altitude of 1450 m and Egirdir/Isparta in Mediterranean region of Turkey about 1100 m in july 2012. The fresh materials were carried in frozen bags to laboratory and then stored at -20 ºC. Voucher specimen is deposited at Herbarium of the Forest Botany Department of Suleyman Demirel University as F4859 and F4865.

Profiles of the Essential Oils and Headspace Analysis of Volatiles from Mandragora autumnalis Growing Wild in Tunisia

“…β ‐Vetivone ( 47 ) and hexahydrofarnesyl acetone ( 48 ), characterizing the leaf EO analyzed in the present study, were identified in the highest relative percentages. The first one is used as a flavor and a fragrance, and has a fresh jasmine odor …”

“…The first one is used as a flavor and a fragrance, and has a fresh jasmine odor. [84] A total of nine aldehydes were identified in the headspaces of the analyzed mandrake organs. Hexanal (34), 2-ethyl-2-hexenal (37), nonanal (38) and 2-butyl-2-octenal (42) were present in the highest amounts.…”

Chemical composition, antibacterial, antifungal and antioxidant activities of Taxus baccata essential oil from Algeria

“…T. baccata chemical composition is very different from the composition of the same species studied elsewhere. The populations of Turkey present as major components 1octene-3-ol, caryophyllene oxide, and hexahydro farnesyl acetone (Yasar 2013) In Serbia, the essential oil of T. baccata is rich in 1octene-3-ol, (3Z) -hex-3-en-1-ol and myrtenol (Stefanovic et al 2016). Another study carried out in Serbia by Radulovic et al (2011) showed that the essential oil of T. baccata exhibits high concentrations of hexahydrofarnesyl acetone, myrenol, (Z) -3-hexenol, senecioic acid and tricosane.…”

“…Radulovic et al (2011) in a study on aerial parts of T. baccata, showed that the essential oil is rich in hexahydrofarnesyl acetone, myrtenol, (Z)-3hexenol, 3-methyl-2-butenoic acid and tricosan. The oils from the fresh leaves of T. baccata collected from the Aegean and Mediterranean region of Turkey are dominated by 1-octen-3-ol, (E)-2-hexen-1-ol, caryophyllene oxide, hexahydrofarnesyl acetone and 1-hexanol (Yasar 2013). The essential oils of T. wallichiana leaves contain 3-hexen-1-ol, 2-hexenal, 1-octen-3-ol, 3-octanone and hexadecanoic acid as the main products (Jian-chun et al 2012).…”

Chemical Composition of Taxus baccata L. Leaves and Male Cones Water:Methanol Extracts

“…One of the means to protect this species is to use the re-growing parts of the plant and also finding and applying the component extraction method is of vital importance [10]. Plant species, habitat environment, and height and the method used to extract the components are effective factors in determining the type and amount of components [11,12]. This study aimed to extract the leaf and male cones components of yew and identify its constituents to provide a better perspective about the T. baccata growing in Iran.…”
