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.

Inorganic constituents in barks of Abies bornmülleriana and Castanea sativa

Barks of Abies bornmülleriana and Castanea sativa were investigated for inorganic constituents by flame atomic absorption spectrometer. 18 elements were detected in the barks of the two species. While Ca was found as the main constituent, 68.7% of the total elements in fir and 76.6% in chestnut, K,Mg,Al and Mn were seen as other predominating elements.
