Yields and Constituents of Essential Oil from Cones of Pinaceae spp. Natively Grown in Turkey

In this study, the yields and composition of essential oils obtained from the cones of Pinaceae family species natively grown in Turkey were investigated. Essential oils were obtained by hydrodistillation. Oil yields were 0.13-0.48 mL/100 g in pine cones, 0.42-0.59 mL/100g in fir, 0.36 mL/100g in spruce and 0.37 mL/100g in cedar. While α-pinene (47.1-14.8%) was the main constituent of P. slyvestris, P. nigra and P. halepensis, limonene (62.8%) in P. pinea and β-pinene (39.6%) in P. brutia were found in higher amounts. Like in P. pinea, limonene was the main compound in Cedrus libani (22.7%). In fir species the major compounds were α-pinene (70.6-53.0%) and β-pinene (10.9-8.2%). Contrary to other species β-pinene (32.7%) was found as a major compound in Picea orientalis.

Yaban mersini (Myrtus communis L.) yaprak ve meyvelerinin uçucu bileşenleri

Bitkilerden elde edilen ucucu yaglar farkli endustri kollarinda bilimsel ve ticari amacli olarak kullanilmaktadir. Bu bakimdan ucucu bilesenlere sahip bitkiler daima arastirmalarin odaginda kendisine yer edinmistir. Mersin bitkisi (Myrtus communis L.) cok genis alanda yayilis gostermekte, ucucu yaginin ve dolayisiyla sahip oldugu ucucu bilesenlerin varligi bilinmektedir. Bu calismada mersin yaprak ve meyve orneklerinin ucucu bilesenleri SPME yontemiyle belirlenmistir. Yaprakta toplam 42, meyvede ise 40 bilesen tespit edilmistir. Limonene meyvede % 40,87 yaprakta % 35,13, α -pinene yaprakta % 26,81, meyvede %19,91, linalyl acetate yaprakta % 8,88, meyvede % 7,57 ve eucalyptol yaprakta % 4,91, meyvede ise % 5,68 ile en fazla tespit edilen bilesenlerdir. Elde edilen sonuclar Turkiye’den farkli bolgelerden temin edilen mersin yaprak ve meyve orneklerinde farkli ucucu yag elde etme yontemleri ile yapilan calismalarla karsilastirmali olarak verilmistir.Plant volatile oils are used in different industrial areas with scientific and commercial purposes. In this case, plants having volatile compounds have always placed themselves in the center of research. Myrtle (Myrtus communis L.) spreads in a very large area and the presence of volatile oil therefore the volatile compounds it has are known. Volatile components of myrtle leaves and berries were determined by solid phase micro extraction (SPME). Totally, 40 components in leaves and 38 components in berries were identified by GC-MS. Limonene 35,13 % in leaves, 40,87 % in berries, α-pinene 26,81 %in leaves, 19,91 % in berries, linalyl acetate 8,88 % in leaves, 7,57% in berries and eucalyptol 4,91 % in leaves 5,68 % in berries were determined as the major compounds. Results compared with different methods of obtaining volatile oils in myrtle leaves and berries gathered from different regions of Turkey.
