The composition and the antibacterial activity of the essential oil, isolated by hydrodistillation from the wood burl parts of Tetraclinis articulata from Morocco, were analyzed by GC and GC/MS. Fifteen compounds accounting for about 96% of the oil were positively identified. Cedrene (23%), thymol (22%), 3-tert-butyl-4-methoxyphenol (19%), cedrenol (9.6%), muurolene (5.4%), and sclarene (3%) were found to be the main constituents. The essential oil was tested for antimicrobial activity against four different genera of bacteria: Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae and Streptococcus D. and exhibited considerable inhibitory effects against all bacteria tested with MIC and MIB close to 1.25 μl/mL. The findings of the present study suggest that Tetraclinis articulata oil from hydro-distillation of sawdust from burl wood collected from artisans, has a potential to be used as bactericide.
