ABSTRACT: 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.
