Essential oil composition of different aerial parts of Pistacia terebinthus L. growing wild in Sardinia

Essentials oils from different aerial parts of Pistacia terebinthus L. growing wild in Sardinia were analyzed in a single GC and GC/MS run. The oil yields obtained from the different parts range from 0.01-1.5%. alpha-Pinene was the main constituent of each of the P. terebinthus oils with the twig oil containing the highest concentration of 66.0%. In fruitful twigs the alpha-pinene concentration was 54.8% while in the leaf oil it was 16.4%. The other major component was beta-pinene, the level of which in the oils of fruitful twigs and leaves was 22.5% and 13.5%, respectively.
