Chemical Composition of Essential Oils from Bark and Leaves of Pinus brutia Ten. from Turkey

Abstract

The chemical composition of essential oils obtained by hydrodistillation of leaves and bark of Pinus brutia was investigated by GC and GC-MS. The essential oil content was 0.8 % (v/w), 0.7 % (v/w), respectively. In the leaf oil of Pinus brutia, b-pinene (29.5 %), germacrene D (17.9 %), a-pinene (14.4 %), b-caryophyllene (9.8 %) were the main constituents. In the bark oil Pinus brutia, a-pinene (14.9 %), b-caryophyllene (11.2 %), d-3-carene (9.6 %), caryophyllene oxide (6.9 %) as the major constituents. A total of 95 compounds have been identified constituting 86.3 % bark, 94.1 % leaves in the essential oils.
