Abstract
ABSTRACT This study aimed to evaluate the chemical and antibacterial properties of the essential oil of B. dracunculifolia from three regions of Brazil: Midwest, Southeast and South region. The major compounds of essential oil from Midwest region were (E)-nerolidol (28.15%) and spathulenol (17.68%), both oxygenated sesquiterpenes. And the major compounds of essential oils from Southeast and South regions were (E)-nerolidol (12.75–13.95%), bicyclogermacrene (10.76–14.21%) and limonene (10.49–19.36%). The three essential oils showed antibacterial activity for both Gram-positive and Gram-negative bacteria tested, with MIC values from 0.03 to 0.15 mg/mL and MBC values from 0.05 to 0.30 mg/mL. The B. dracunculifolia essential oil from the Midwest region of Brazil presented higher values of oxygenated sesquiterpenes and was more effective on all tested bacterial strains, with lower and statistically significant MBC values, compared to the oils from the Southeast and South regions of Brazil
期刊介绍:
Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include:
-Analytical chemistry-
Biological activity-
Biotechnology-
Chemical composition-
Chemical synthesis-
Chemosystematics-
Microbiological activity-
Plant biochemistry/biosynthesis-
Toxicology.
Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
