“…Also, the yield of EOs from leaves of C. sempervirens L. obtained in this study was lower than that reported by Mazari et al (2010); Elansary et al (2012) and Amri et al (2013), and lower than the yield of EOs from cone of Tunisian C. sempervirens L. which reported by Ben Nouri et al (2015). The yield of EOs isolated from leaves of J. phoenicea L. obtained in this study was lower than that reported by Stasis et al (1996); Mazari et al (2010); Derwich et al (2010) and Amalich et al (2015), but it was relatively similar when compared to that reported by Angioni et al (2003) and Achak et al (2009). 2.…”

The present study reports the variation in the essential oils (EOs) composition from needles and scale leaves of Pinus halepensis, Cupressus sempervirens and Juniperus phoenicea which collected from three different altitudes at Al-Jabel Al-Akhdar area, Libya. The impact of the altitude on the quantity and quality of EOs was studied. In addition, the antibacterial activity was evaluated using microdilution broth assay technique. The results showed that the highest percentages of the EOs yield were found in P. halepensis with 0.41, 0.60, and 0.43% for the altitudes of 125m (I), 391m (II), and 851m (III), respectively, while the lowest percentages of the yield were found in J. phoenicea, with 0.15, 0.07, and 0.18% at altitudes of I, II, and III, respectively. Based on P. halepensis EOs analyses using GC/MS, 35 components have been detected, which represents 89.92, 91.56, and 86.44% for the altitudes of I, II and III, respectively. Furthermore, high percentages from the components of α-pinene, β-pinene, α-terpineol and caryophyllene were identified at the three tested altitudes. For C. sempervirens EOs, 33 components were identified representing 84.94, 93.37 and 99.48% for levels I, II and III, respectively. The highest percentages of the EOs components in this species were α-pinene, terpinen-4-ol and α-terpiny acetate at the three tested elevations. However, the detected main components in J. phoenecea EOs were α-pinene, α-myrcene, α-terpinyl acetate and γ-terpinene. The highest antibacterial activity was observed for the oils from P. halepensisat and J. phoenicea at altitude I against the Agrobacterium tumefaciens, Erwinia carotovora, Corynebacterium fascians and Pseudomonas solanacearum. While the EOs extracted from scale leaves of C. sempervirens obtained from trees growing at level II were the most active against the tested bacteria. The results of this work revealed the impacts of the environmental conditions on the EOs composition which affected significantly in its quantitative and qualitative performances. Consequently, their biological activities were varied considerably. Moreover, the obtained data offer the opportunity to choose EOs with preferential compound for pharmaceutical, pesticides, perfume and food industries in such important region in Libya.

“…The Barbary thuja, Tetraclinis articulata (Vahl) Masters, a member of the Cupressaceae family, is an endemic species of North Africa (Morocco, Algeria, and Tunisia). Outside this zone, we find small localities in southeastern Spain (Cartagena province) as well as Malta Island 1 . The surface area of Tetraclinis woodlands is estimated at 565 798 ha, which represents approximately 10% of the total forest cover in Morocco and the majority of the Moroccan Tetraclinis areas are more likely to be in the temperate and warm semi-arid bioclimatic zone.…”

The quality and the variability of the chemical composition and antimicrobial properties of essentials oils isolated from Tetraclinis articulata (Vahl) leaves, which were studied from two different regions that are ecologically various. The average yield of essential oil is 0,56 % for the Ras Elma Tazekka region (mountain) and 0,36% for the Debdou region (plain). An analysis made by GC and GC/ MS identified 22 components in Tetraclinis articulata leaves essential oil in the mountain area and 29 components in the plain area. These major components represent the variability of quantity. The percentages following respectively by the two areas are: Bornyl acetate (34,84%; 32,55%), α-Pinene (11,41%; 18,83%), Camphor (11,24 %; 11,31%), Limonene (11,94 %; 8%) and Borneol (8,35%; 7,79%). The antimicrobial activity of T. articulata essential oil was tested against clinical isolates of Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli which has been inhibited from the 50μg / mL concentration for the Debdou region (Plain) and 25μg / mL for that of the Ras Elma Tazekka region (Mountain).

“…The identification of the compounds was performed by comparing their retention indices and mass spectra with those found in the literature [10][11][12] and supplemented by the data system library of NIST. The relative proportions of the essential oil constituents were expressed as percentages obtained by peak area normalization, all relative response factors being taken as one.…”

Cupressus atlantica Gaussen, an endemic species from Morocco, is used in traditional medicine. The chemical composition of the essential oil isolated by hydrodistillation from the leaves was investigated by capillary gas chromatography and gas chromatography/mass spectrometry, and also evaluated for in vitro antimicrobial activity. Sixty-one components, representing 98.1% of the total, were detected of which fifty-seven were identified. Germacrene D (34.8%), α-pinene (13.6%), δ-cadinene (6.1%), α-phellandrene (5.5%), γ-cadinene (5.0%), β-caryophyllene (4.8%) and α-humulene (4.4%) were the predominant compounds. The oil was characterized by a relatively high amount of oxygenated monoterpenes (66.5%). The oil, screened for antimicrobial activity against both Gram-positive and Gram-negative, showed pronounced activity against all the microbes tested, except Pseudomonas, which showed resistance.
