    ABSTRACT: The chemical composition of the Tamarix boveana volatile oils obtained from the whole aerial part, flowers, leaves and stems by steam distillation was analysed using gas chromatograph (GC)-flame ionization detectors (FID) and GC-MS. Sixty-two components were identified. Hexadecanoic acid (18.14%), docosane (13.34%), germacrene D (7.68%), fenchyl acetate (7.34%), Benzyl benzoate (4.11%) were found to be the major components in the whole aerial parts. This composition differed according to the tested part: 2.4 Nonadienal was the main compound in the flowers (12.13%) while germacrene D was the major component in leaves (31.43%) and hexadecanoic acid in the stems (13.94%). To evaluate in vitro antimicrobial activity, all volatile oils were tested against six Gram-positive and Gram-negative bacteria and four fungi. The T. boveana volatile oils exhibited an interesting antibacterial activity against all strains tested except Pseudomonas aeruginosa but no antifungal activity was detected.

    ABSTRACT: The chemical composition of the essential oils obtained by hydrodistillation from leaves, branches and female cones of Cupressus arizonica Greene cultivated in Tunisia was determined by GC and GC/MS analysis. Significant differences were found between the constituent percentages of the different oils. Among the 87 identified components α-pinene (60.5% in female cones), umbellulone (18.4% in leaves), δ-3-carene (15.6% in branches) and cis-muurola-4(14),5-diene (9.4% in leaves) were found to be the major ones.Composition of essential oils extracted from different organs of C. arizonica Greene growing in Tunisia showed remarkable differences from the same species cultivated in Algeria, Argentina, Iran, Italy, France and Texas based on a comparison with published results. The in vitro antibacterial activity of the essential oils samples was evaluated against some Gram positive and negative bacteria.
