The yields of essential oils reached 0.86 for male and 0.65 for female. Fifty compounds were revealed and used in the oil characterization. The main compounds in oil of female foliage were sabinene, γ-terpinene, δ-2-carene, and terpinene-4-ol. In addition, eight compounds were revealed in female plants only. On the other hand, sabinene and trans-sabinyl acetate were identified as the major constituents, and seven compounds were detected exclusively in the oil of male individuals. The oils of Algerian populations of Juniperus sabina revealed a chemical composition which is closer to the Iberians populations comparatively to those of central Europe and Asia. Two components i.e. safrole and methyl eugenol were detected in essential oil of Algerian and also reported by litterature data on Iberian populations.
