Antimicrobial activity of Tetraclinis articulata aerial parts essential oil from Tlemcen, Northwestern of Algeria

Abstract

The essential oil from aerial parts of Tetraclinis articulata (Vahl) Masters, obtained byhydrodistillation was analyzed by GC, GC/MS and 13C-NMR and evaluated for antimicrobialactivity. The essential oil was rich in monoterpenes which α-pinene, bornyl acetate andcamphor being the main constituents.Three essential oils were tested against Staphylococcusaureus, Enterococcus faecalis, Pseudomonas aeruginosa, Escherichia coli, Klebsiellapneumoniae, Candida albicans, Aspergillus fumigatus and Aspergillus flavus and theminimum inhibitory concentration was determined.The tested oils have been shown topossess inhibitory action in the range from 1 to 6 µL/mL against Aspergillus fumigatus, A.niger and Staphylococcus aureus. However, essential oil with camphor as major componentwas the most interesting, with CMIs ranging between 1 and 3 µL/mL. While, essential oilwith α-pinene as major compound, remains the less effective, with CMIs ranging between 2and 6 µL/mL.
