Chemical constituents of the essential oil from the leaves of Minthostachys mollis (Kunth) Griseb Vaught var. mollis collected in January 2008 at Tuñame, Trujillo State, Venezuela, were separated and identified by GCMS analysis. The essential oil was obtained by hydrodistillation and thirteen components (98.5% of the sample) were identified by comparison with the Wiley GCMS library data base. The two major components were pulegone (55.2%) and trans-menthone (31.5%). The essential oil showed a significant inhibitory effect against Gram-positive and Gram-negative bacteria, especially Bacillus subtilis and Salmonella typhi (4 μg/mL).

Objective: Streptococcus oralis plays an important role in the biofilm formation of dental plaque and the occurrence of periodontal disease. Thepresent study was conducted to evaluate in vitro antibacterial activity of three essential oils, namely, Cinnamomum zeylanicum, Eugenia caryophyllata,and Rosmarinus officinalis against S. oralis.Methods: The antibacterial activity of essential oils was investigated by diffusion method using sterile discs (or aromatograms). The minimuminhibitory concentration (MIC) of essential oils showing important antibacterial activity was measured using the broth dilution method.Results: Evaluation of the antibacterial activity of three essential oils as determined by the aromatogram technique showed that the essential oilof R. officinalis had no effect on S. oralis, while the latter was extremely sensitive to the other two essential oils, but with a higher efficiency of theessential oil of C. zeylanicum (42 mm diameter) than E. caryophyllata (20 mm diameter). Similarly, the MIC and minimum bactericidal concentration(MBC) were higher for the essential oil of C. zeylanicum than the essential oil of E. caryophyllata. The MBC/MIC ratio is of the order of 2. The essentialoils studied therefore appear to exert bactericidal activity against S. oralis.Conclusion: The findings suggest that essential oils of C. zeylanicum and E. caryophyllata may be used as an alternative to synthetic antibiotics.Keywords: Essential oil, Cinnamomum zeylanicum, Eugenia caryophyllata, Rosmarinus officinalis, Antimicrobial activity, Streptococcus oralis.

The chemical constituents of the essential oil obtained by hydrodistillation from the leaves of Calycolpus moritzianus (O. Berg) Burret, syn Psidium caudatum Mc Vaught, collected in November 2006 in Mérida State, Venezuela, were identified by GC-MS analysis. Thirty components (91.1% of the sample) were identified, of which the seven major ones were β-caryophyllene (21.9%), α-pinene (10.9%), viridiflorol (9.7%), β-selinene (6.1%), α-copaene (6.3%), α-selinene (5.3%) and γ-eudesmol (5.1%). The oil was found to have antibacterial activity against Staphylococcus aureus ATCC (6538) and Enterococcus faecalis ATCC (29212), with MIC values of 60 μg/mL and 180 μg/mL, respectively.

Antagonistic Interactions

The chemical composition and antibacterial activity of Nepeta nuda (Lamiaceae) essential oil were examined, as well as the association between it and standard antibiotics: tetracycline and streptomycin. The antibacterial activities of 1,8-cineole, the main constituent of N. nuda oil, individually and in combination with standard antibiotics were also determined. The interactions of the essential oil and 1,8-cineole with antibiotics toward five selected strains were evaluated using the microdilution checkerboard assay in combination with chemoinformatics methods. Oxygenated monoterpenes were the most abundant compound class in the oil (57.8%), with 1,8-cineole (46.0%) as the major compound. The essential oil exhibited in vitro antibacterial activity against all tested bacterial strains, but the activities were lower than those of the standard antibiotics. The combinations N. nuda oil-antibiotic and 1,8-cineole-antibiotic produced a predominantly antagonistic interactions. Chemoinformatics survey confirms the antagonistic interactions as a consequence of membrane potential/proton motive force dissipation. These data indicate cytochrome c oxidase as a target for 1.8-cineole toxicity action mechanisms.
