Resumen
The antimicrobial activities of plant extracts have formed the basis of many alternative medicines. In this context, the genus Schinus L. (Anacardiaceae), exhibits many traditional uses in medicine. However, a few studies on the antimicrobial properties of Schinus areira essential oils were conducted. The essential oil from S. areira leaves from Santiago del Estero was obtained by hydrodistillation and twenty-eight compounds were identified using CG-MS-EI spectrometry. The sesquiterpenoid alcohol 1-epi-cadinol was the major compound, followed by δ-cadinene, alloaromadendrene, β-pinene, β-caryophyllene, and γ-cadinene. The essential oil obtained exhibited antimicrobial activity against Staphylococcus aureus, showing a bacteriostatic activity at 64 µg/mL and bacteriolytic activity at 256 µg/mL; in contrast, non antibacterial effect was observed in Escherichia coli in the assayed conditions. The antibacterial activity was accompanied by significant changes in Zeta potential on the S. aureus surface. The data obtained suggest that the essential oil of S.areira leaves presents potential use in pharmaceutical industries.
