“…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.

Herein we report the extraction of labdane-type diterpenoids from the needles of the common juniper (Juniperus communis ssp. communis var. communis L.), and identification of them as the major class of compounds in this species. Furthermore, and to the best of our knowledge we provide the first-ever report some of these compounds (nor-16-imbricatolic, nor-16-acetylimbricatolic and acetylimbricatolic acids) as natural compounds. Imbricataloic and imbricatolic acids were the most abundant compounds, accounting for 65% of the total extract. We also found long-chain secondary alcohols (n-alkan-10-ols) and secondary/secondary alkanediols (4,10-, 5,10-, 6,10-, 7,10-), which we report here for the first time ever in the genus Juniperus. In total, we identified 127 compounds: of these, 48 (nonacosan-10-ols, -tocopherols and lignans) are described here for the first time in Juniperus and 54 (including alkanols, phytol, sterols and flavonoids), for the first time in common juniper. Highlights 127 phytochemical constituents of the needles of Juniperus communis were investigated with imbricatolic and imbricatalic acid as the most abundants  3 Labdane-type diterpenoids are new natural products  17 compounds have no precedent in Juniperus genus and 32 are described for the first time from Juniperus communis Keywords: Juniperus communis; Common juniper; Diterpenoids; Labdane-type; Alkanediols; Imbricatolic acid; Gas chromatography-Mass spectrometry (GC/MS); Trimethylsilyl (TMS) ether derivatives. IntroductionThe genus Juniperus (Cupressaceae) comprises 68 species and 36 varieties growing principally in the northern hemisphere . The chemical composition of the genus Juniperus has been extensively reviewed by Seca & Silva (2006). Table 1 summarizes the phytochemical characteristics of the principal compounds from the genus Juniperus, excluding terpenes, secondary alcohols and secondary diols, which we discuss separately in a latter section.The species Juniperus communis L. comprises four subspecies, including the common juniper (J. communis ssp. communis), a coniferous evergreen shrub that has a broad geographic range throughout the holarctic region. In fact, it exhibits the largest range of any woody plant, spanning the cool, temperate, part of the Northern Hemisphere: from mountains in the southern arctic, to roughly 30ºN latitude in North America, Europe and Asia. It tolerates a variety of climatic and edaphic conditions. The surface layer of plant leaves typically contains many classes of compounds, including alkanes, primary alcohols, acids, aldehydes, terpenes and phenols. However, there are very few reports on the overall composition of common-juniper needles. Thus, in the study reported here, we sought to analyze the soluble fraction of common-juniper needles.We analyzed the total extract of common-juniper needles and identified each wax-class of compounds, discovering many acyclic and cyclic compounds from three major groups: terpenoids (e.g. sesquiterpenes and diterpenes); phenols (including phenolic acids,...

Antimicrobial activity and chemical composition of the essential oil of Juniperus communis (L.), originated from east part of Kosova, was investigated. The essential oil from berries of J. communis (L.), obtained by hydro-distillation was analyzed by GC and GC-MS. Antimicrobial properties of the essential oil of J. communis (L.) are investigated and results are submitted for their activities against Staphylococcus aureus, Escherichia coli, Hafnia alvei and Pseudomonas aeruginosa. Applying the agar disc diffusion technique, we measured diameters of the inhibition zone around discs, which are previously wetted with DMF solution of the essential oil with three different concentrations, 1, 3 and 5 mg mL −1 . Analysis of the oil resulted in the identification of 41 peaks, representing 96% of the oil. Berry essential oil composed mainly of monoterpenoids which amounted to 83%, of which 69.4% was monoterpene hydrocarbons. The main monoterpene hydrocarbons were α-pinene (36.2%) and β-myrcene (21.1%). The sesquiterpene accounted for about 13.4% of the total oil composition. Germacrene D (2.2%), α-cadinol (1.6%), α-humulene (1.5%), spathulenol (1.4%), epi-α-bisabolol (1.3%) and germacrene B (1.1%) were the main constituents of the sesquiterpenes. The inhibition zone depends from concentrations and also from sort of bacteria. The inhibition zones differ from 0-39 mm. The present work presents the chemical composition of the hydrodistilled oil of J. communis (L.) from East part of Kosova and the results are compared to those reported in the literature. This study demonstrates the occurrence of α-pinene chemotype of J. communis (L.) from east part of Kosova. The essential oil of J. communis (L.) growing wild in Kosova, showed moderate to high activities against Staphylococcus aureus, Escherichia coli, Hafnia alvei. Pseudomonas aeruginosa is resistant to the essential oil of J. communis (L.) growing wild in east part of Kosova.
