Abstract

Isolation of oils from leaves of Juniperus phoenicea and Juniperus oxycedrus was obtained by steam distillation extraction method. The compositions of essential oils (EOs) were studied by means of GC-MS and GC-FID, using the internal standard method and relative response factors. Around ninety eight compounds were determined in total, representing 98.25 g/100 g of EO of J. phoenicea and 98.48 g/100 g of EO of J. oxycedrus, respectively. The volatile leaf oils were dominated by the terpenic hydrocarbon fractions (79.87 g/100 g) and (61.27 g/100 g) characterized by high contents of α-pinene (64.6 g/100 g) and (54.0 g/100 g) in J. phoenicea and J. oxycedrus, respectively, as the main component. Also, the enantiomeric distribution of α-pinene, sabinene, camphene, δ-3-carene, β-pinene, limonene, linalool, terpinen-4-ol, bornyl acetate, and borneol in both oils is presented for the first time.
