The search for new antibiotic agents from plants is growing, and no study regarding the activity of C. jamacaru pathological microorganisms has been carried out. This research evaluates the antibiotic effect of crude ethanolic extracts of the cortex (EBCO) and wood (EBLE) of the species over eight microorganisms. Two methods were used: agar diffusion and MIC (minimal inhibitory concentration). EBCO showed better inhibition results than EBLE. Streptococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli are the microorganisms that were better inhibited by EBCO.
