Abstract

The objective of this work is to determine the chemical composition of essential oils of four Cupressaceae species and to bring out some of their antimicrobial activities. For this purpose, the extraction of essential oils was carried out by Hydrodistillation and the obtained oils varied from 0. 4% to 0. 91%, with a better yield for Cupressus sempervirens equal to 0. 91%. The chromatographic analyses revealed that the chemical composition of Juniperus phoenicea, Juniperus oxycedrus and C. sempervirens is largely dominated by monoterpenes at rates higher than 34% with majority of α-pinene like component. In addition, the results of the antibacterial activity showed a significant inhibitory effect of essential oils, particularly those of J. phoenicea was found to be the most active with values of Minimum Inhibitory Concentration (MIC) equal to 50μ g/ml. Moreover, the mycelial growth inhibition confirms that essential oils of J. phoenicea and J. oxycedrus are most effective, with values of MIC equal to 1000μ g/ml for both. These antimicrobial properties would be due to the richness of these essences in bioactive compounds such as the terpenoids, polyphenols and alkaloids known for their implication in the plants selfdefense. Consequently, the inhibitory effect of these essential oils on the microbial development suggests prospects for their application as natural and safe alternatives to synthetic compounds for plant protection.
