Chemical Composition of the Essential Oils ofPistacia atlanticaDesf.

The chemical composition of the three essential oils obtained by hydrodistillation of the resin, leaves and fruits of Pistacia atlantica Desf. (Anacardiaceae) was studied by GC and GC/MS. Monoterpene hydrocarbons constituted the main chemical group in the resin oil, with α-pinene (42.9%) and β-pinene (13.2%) as the major components. Oil of the fruits contained high amounts of oxygenated monoterpenes, with bornyl acetate (21.5%) as the major component, while oxygenated monoterpenes and sesquiterpenes were found to predominate in the oil of leaves among which terpinen-4-ol (21.7%) and elemol (20.0%) were the most abundant components.
