Abstract
Background
Cordia verbenacea is a Brazilian coastal shrub popularly known as “erva baleeira”. The essential oil from fresh leaves was obtained by hydrodistillation and analyzed by CG/MS. The main components were identified as b-caryophyllene (25.4%), bicyclogermacrene (11.3%), q-cadinene (9.%) and a-pinene (9.5%). In this study, the antimicrobial activity of Cordia verbenacea was evaluated.
Materials and Methods
The minimal inhibitory concentration (MIC) of the essential oil was obtained using the broth microdilution assay (from 512 to 8 μg/ml).
Results
The results showed that the essential oil presented fungistatic activity against Candida albicans and Candida krusei and antibacterial activity against Gram-positive strains (Staphylococcus aureus and Bacillus cereus) and against multiresistant Gram-negative (Escherichia coli 27), in all tests the MIC was 64 μg/ml. When the essential oil was associated to aminoglycosides (subinhibitory concentrations, MIC/8), a synergic and antagonic activity was verified. The synergic effect was observed to the amikacin association (MIC reduction from 256 mlto 64 μg/ml) in all strains tested.
Conclusion
The essential oil of Cordia verbenacea influences the activity of antibiotics and may be used as an adjuvant in antibiotic therapy against respiratory tract bacterial pathogens.
