Abstract

In the present study, Cedrus atlantica leaves volatile oil were screened for their antibacterial activity and chemical composition. The essential oil chemical constituents obtained by hydro-distillation and analyzed by gas chromatography coupled with mass spectrometry (GC-MS). The antibacterial activity was tested in vitro on Gram-negative bacteria: Escherichia coli, Pseudomonas and Klebsiella pneumonia and Gram-positive: Staphylococcus aureus, Bacillus, and Enterococcus faecalis, using disc-diffusion method. Twenty five compounds were identified in leaves oil representing 66.0.9 % of the total oil composition. Cedrus atlantica essential oil yield was 1.64% and major compounds were α-pinene (8,65%), himachalene (8.41%), β-himachalene (8,14%), σ-himachalene (6,26%), cis-α-atlantone (5,11%), himachalol (4,25%) and α-himachalene (3,25%), germacrene D (3.15%), β-caryophyllene (2.14%), cadinene (2.00%), β-pinene (1.95%), humulene (1.20%) and β-copaene (1.16%). In both strain, Cedrus atlantica oil exhibited very considerable antibacterial activity.
