In this study we describe the extraction, chemical composition, and antibacterial
activity of the essential oil extracted from fruits of Pimenta dioica. For this, we
extracted the oil by hydrodistillation; we identified the compounds by Gas Chromatography coupled to the Mass Spectrometer (CG/MS); we quantified the major
component by vis-UV Spectrometry and Voltammetry; and we determined the
antibacterial activity against Escherichia coli, Staphylococcus aureus, Proteus mirabilis,
Pseudomonas aeruginosa, and Serratia odorifera, using the disk diffusion method.
The results showed that the oil is composed mostly of eugenol and its quantity is
approximately 78.15%, whose predominant class was that of monoterpenes. In addition, the bacteria tested with the essential oil showed inhibition halos, ranging from
11 to 21 mm. Therefore, the oil is a potential antibacterial agent. |
