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.

This work was performed to determine the biochemical composition, antioxidant and antimicrobial activities of leaf extracts collected from four different provenances: Mahdia and Mahres (Ziziphus jujuba); Kairouan and Rouhia (Ziziphus lotus). Total phenols, flavonoids, tannins contents and antioxidant activity were evaluated using the Folin ciocalteux, Aluminum trichloride, vanillin and scavenging activity on 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radicals methods, respectively. The antimicrobial activity was evaluated against three bacterial strains (Escherichia coli, Staphylococcus aureus and klebsiella pneumoniea) and three fungal strains (Fusarium culmorum, Fusarium solani and Botrytis cinerea), according to well Agar diffusion method. Total phenols and flavonoids were present at levels of 21.98 mg GAE /g DW and 7.80 mg ER/g DW; respectively in Ziziphus lotus. These levels did not exceeded 13.70 mg GAE /g DW and 6.73 mg ER/g DW for Ziziphus jujuba. The tannin contents were present in equal levels (7.9 mg EC/g DW) in two species. The high antioxidant activity (0.01 µg/ml) was noted in Rouhia provenance. The Ziziphus lotus leaf extracts showed promising efficiency against all tested microorganisms with a zone of inhibition ranging between 22 and 23.5 mm. This study could validate the medicinal potential of Ziziphus specie and explain why tunisian people traditionally use it in medicine to treat several pathologies. Ziziphus leaf extracts may be suggested in foods and pharmaceutical industries. Leaf extracts proved also to be effective against tested microorganisms. So, an adequate toxicological study must be carried out to verify the possibility of using these plants for fighting microorganisms.

The composition of oil samples isolated from needles of Pinus halepensis growing in three locations in Corsica (Saleccia, Capo di Feno and Tre Padule) has been investigated by combination of chromatographic (GC with retention indices) and spectroscopic (MS, C-NMR) techniques. In total, 35 compounds that accounted for 77-100% of the whole composition have been identified. α-Pinene, myrcene and (E)-β-caryophyllene were the major component followed by α-humulene and 2-phenylethyl isovalerate. Various diterpenes have been identified as minor components. Forty seven oil samples isolated from pine needles have been analyzed and were differentiated in two groups. Oil samples of the first group (15 samples) contained myrcene (M= 28.1g/100g; SD = 10.6) and (E)-β-caryophyllene (M = 19.0g/100g; SD = 2.2) as major components and diterpenes were absent. All these oil samples were isolated from pine needles harvested in Saleccia. Oil samples of the second group (32 samples) contained mostly (E)-β-caryophyllene (M = 28.7g/100g; SD = 7.9), α-pinene (M = 12.3g/100g; SD = 3.6) and myrcene (M = 11.7g/100g; SD = 7.3). All these oil samples were isolated from pine needles harvested in Capo di Feno and Tre Padule. This article is protected by copyright. All rights reserved.
