摘要
The Schinus terebinthifolius Raddi is a native plant of South America popularly known in Brazil as aroeira. It is a medium-sized plant, which demonstrates a high adaptive potential in various environments, besides having various medicinal properties such as anti-inflammatory and antidiarrheal. Bacterial susceptibility tests were carried out and the minimal inhibitory concentration (MIC) was obtained. The results were interpreted based on the conventionally microbiological protocols and data from the CLSI. For the microbiological tests, microorganisms obtained from the American Type Culture Collection (ATCC), specifically, (Pseudomonas aeruginosa, Staphylococcus aureus and Encherichia coli) were used. Of the tested bacterial strains, only the Staphylococcus aureus 6538 presented susceptibility to the aroeira’s hydroalcoholic extract, forming zones of inhibition of 8.0 mm of diameter up to the MIC of 35.3 mg/mL, while the other tested strains showed to be resistant in all the concentrations of hydroalcoholic extract of the Schinus terebinthifolius Raddi bark. Our aim is to analyze the “in vitro” antibacterial potential of the 70% hydroalcoholic extract of the Schinus terebinthifolius Raddi.
