This study was designed to examine the chemical composition of the essential oil and the in vitro antibacterial activities of the essential oil and methanol extract of Teucrium montanum. The inhibitory effects of the essential oil and the methanol extracts of Teucrium montanum were tested against thirteen bacterial species using the disc-diffusion method. GC/MS analyses revealed that the essential oil contained mainly sesquiterpenes, such as ?-cadinene (17.19 %), ?-selinene (8.16 %) and ?-calacorene (4.97 %). The highest activities were obtained with the essential oil of Teucrium montanum against K. pneumoniae, B. subtilis, B. mycoides, E. cloaceae and A. chlorococcum. In addition, comparison of the antibacterial activities of the essential oil and the methanol extract showed that the essential oil exhibited the stronger antibacterial activities.

Foeniculum Vulgare

Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.

In the present study, chemical composition and antibacterial properties of essential oil obtained from the aerial parts of the Melicope pteleifolia (Champ. ex Benth.) T.G Hartley in Dalat were evaluated. Essential oil was isolated through hydro-distillation. Twenty-nine constituents comprising 100% of the essential oil were characterized by gas chromatography/mass spectrometry (GC-MS) techniques. The major compounds in the essential oil were (+)-Sabinene (34.73%), Cis-α-bergamotene (13.15%), Z-α-trans-bergamotol (5.28%), β-mycrene (4.98%), and 1,3,6-octatriene, 3,7-dimethyl-(4.71%). Antibacterial activities of Melicope pteleifolia essential oil were investigated against Gram-positive and-negative bacteria. Results showed significant activities against Streptococcus pyogenes and Escherichia coli using an agar well diffusion method. The application of this essential oil in preventing and eliminating bacteria could be useful in fields as medicine and cosmetics.

Chemical composition, antioxidant and antibacterial activities of the essential oil of Curcuma phaeocaulis were analysed. In the aerial part, 22 compounds account for 69.23% of the total essential oil and authenticated, while in the underground part, 32 compounds account for 84.28% of the total essential oil and authenticated. Among the compounds detected, α-pinene, camphene, eucalyptol, camphor, borneol, β- tumerone, epi-curzerenone were the main compounds of volatile oil in both parts of Curcuma phaeocaulis. In addition, various lipid antioxidant properties by peroxidation assays, inoxidizability and antibacterial action were assessed. The result may be considered as a baseline study for the further development and application of Curcuma phaeocaulis.
