“…obtained in our study is lower than that reported by Amri et al (2013) and higher than that reported by Abi-Ayad et al (2011) and Raho (2014) but it was relatively similar to that reported by Dob et al (2005);Fekih et al (2014), and Hamrouni et al (2015). 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).…”

“…Similar result was found by Mazari et al (2010), who reported that α-pinene was the major component of leaves EOs, but it is presented in upper content (60.5%) compared with our study (15.05 , 15.63 and 17.89%). Also the percentage of α-pinene was the same as obtained by Elansary et al (2012) However, compounds of α-cubebene and Tmuurolol were found in scale leaves of trees growing at altitudes of II and III. It is also noted that a carotol was detected in level I and III, respectively.…”

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.

Abstract:The essential oil of Melaleuca alternifolia is an herbal antifungal action and preventive scale pharmaceutical or cosmetic. The aim of this study was to evaluate the efficacy of Melaleuca alternifolia (tea tree oil-TTO) and its component (Terpinen-4-ol) on Candida albicans and Candida tropicalis in planktonic and biofilm form of dual species. MIC (Minimum Inhibitory Concentration) and MFC (Minimum Fungicidal Concentration) were determined of single species. Biofilms were quantified in CFU (colony forming unit per mL) and XTT {2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide} cell viability assay in single and multiple species. MIC was TTO (0.25%) and Terpinen-4-ol (0.11%) for both species. The MFC for Candida albicans showed TTO (0.25%) and Terpinen-4-ol (0.11%) were capable of inhibiting the growth and for Candida tropicalis was 0.50% and 0.24%, respectively. The results on biofilm for Candida albicans in single species and multiple species showed TTO (0.5%) and Terpinen-4-ol (0.24%) were effective. For Candida tropicalis in single species, treatments with TTO (0.5%) and Terpinen-4-ol (0.47%) were effective. For multiple species, the treatments with TTO (0.5%) and Terpinen-4-ol (0.24%) were also effective. In the XTT test, for Candida albicans in single species: TTO (0.25%) and Terpinen-4-ol (0.24%). For Candida tropicalis, the results were TTO (0.5%) and Terpinen-4-ol (0.11%), while for multiple species were TTO (0.25%) and Terpinen-4-ol (0.11%). Based on these factors, Candida spp. are susceptible to the antimicrobial agents TTO and Terpinen-4-ol, suggesting that these compounds might be beneficial as therapeutic.

“…Free radical scavenging activity of the samples was determined using 2,2-diphenyl-1-picrylhydrazyl method (DPPH, Sigma-Aldrich) with some modifications (Elansary et al, 2012). An aliquot of 2 ml of stock solution of 0.1 mM DPPH reagent dissolved in pure methanol was added to a test tube with 2 ml of the sample solution in methanol (200 µg/l).…”

Tecoma stans of the Bignoniaceae family, is an important medicinal plant. Different extracts of the leaves and branches of T. stans were evaluated as antibacterial potential against the growth of some human bacterial strains using the disc diffusion and minimum inhibitory concentration (MIC) methods as well as the antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Total phenolic and total flavonoid contents were determined. The different extracts of T. stans were obtained by successive solvent extraction with methanol and its fractions; ethyl acetate (EtOAc), chloroform (CHCl 3 ), n-butanol and aqueous. The methanol, EtOAc and CHCl 3 extracts of T. stans showed significant effect against the tested bacteria (Bacillus subtilis, Micrococcus luteus, Sarcina lutea, Staphylococcus aureus, Escherichia coli, Serratia marcescens, Salmonella typhi, Proteus vulgaris and Pseudomonas aeruginosa). The methanol extract of the leaves exhibited the highest amount of total phenolics (50.3±3 mg gallic acid equivalents/g extract) and flavonoids (40.66±5.03 mg catechin equivalents/g extract). The EtOAc fraction of leaves and branches extracts showed the highest total antioxidant activity (%) with 83.4±0.31 and 82.06±0.54%, respectively followed by CHCl 3 fraction of leaves extracts (79.17±0.20%). These findings provide scientific evidence to support traditional medicinal uses of T. stans and indicate a promising potential for the development of an antibacterial and antioxidant agent from T. stans trees.
