ABSTRACT
Abstract Our study aimed to evaluate the chemical composition of the essential oil from the leaves of Eugenia pyriformis Cambess., belonging to the Myrtaceae family and native to the Brazilian Atlantic forest. The volatile compounds in the essential oil were extracted by hydrodistillation and analyzed using GC-MS; 36 compounds accounted for 78.80% of the total oil content. The major compounds were β-caryophyllene, bicyclogermacrene, globulol, and (δ-cadinene. We evaluated their antimicrobial potential of the essential oil and toxicity to Artemia salina. The antimicrobial activity of the essential oil was evaluated against 12 microorganisms using the broth microdilution method. Our results showed moderate inhibition of Staphylococcus aureus and methicillin-resistant S. aureus (MIC, 250 and 125 μg.mL-1, respectively) and toxicity to A. salina (LC50, 125.64 μg.mL-1). Our results establish the biological activity of the essential oil obtained from E. pyriformis.
