This study evaluated the toxicity and antimicrobial activity in the face of Escherichia
coli and Staphylococcus aureus of essential oils of Pimenta dioica Lindl. and Citrus
sinensis L. The essential oils (EO) were extracted by hydrodistillation, with chemical
characterization by gas chromatography coupled and mass spectrometry (GC-MS).
Physicochemical parameters were determined according to the Brazilian Pharmacopeia. The toxicity test followed the bioassay with Artemia salina Leach, the EO
approved in this assay followed to evaluate its biological properties. The antimicrobial activity followed the methodology described by the Clinical and Laboratory
Standards Institute using the disc diffusion method, broth dilution for minimum
inhibitory concentration (MIC) and subsequent minimum bactericide concentration for to evaluate the action of EO against Escherichia coli and Staphylococcus aureus.
Both OE showed low toxicity, and thus were evaluated for the biological antimicrobial properties. Both OE presented bactericidal potential against the microorganisms
tested, showing satisfactory results for their action. The results indicate that the evaluated OE are composed of substances that provide and encourage their application
due to their potentials for biological molluscicide and antimicrobial activity. |
