【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2016v29n1p109This study evaluates the antimicrobial activity of tannins observed on the stem bark ofPiptadenia stipulacea(Benth) onStaphylococcus aureusstrains of bovine origin. In vitro antimicrobial activity of the tannin was evaluated by determining the minimum inhibitory concentration (MIC). To determine the MIC, tannins were serially dissolved in distilled water at concentrations ranging between 500 mg/mL and 0.976 mg/mL. Assays were performed in triplicate. Tannins inhibited the growth ofS. aureus , showing 31.25 mg/mL as the MIC value. The results of this study are promising, as they show the importance of evaluating new compounds of natural origin that fight against infections caused byS. aureus . Further studies are needed to confirm in vivo activity and evaluate the action mechanism of tannin isolated from the stem bark ofPiptadenia stipulacea .
