The objective of this work was to evaluate and determine the in vitro antibacterial activity of the ethanolic extract of the bark of Tynanthus panurensis (NAIL HUASCA) against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The vegetal sample was collected from the Experimental Center of Medicinal Plants (Botanical Garden Arboterum) of the Faculty of Agronomic Sciences of the UNAP located in Carretera de Zungarococha; for the evaluation of antibacterial activity in vitro, the disc diffusion method "Kirby-Bauer" and dilution in broth "macrodilution" were used; the antibiotics meropenem, ciprofloxacin, gentamicin and vancomycin were used as positive controls. Results: the in vitro antibacterial activity by the diffusion disc method, at concentrations of 1300 mg / ml, 1500 mg / ml, and 1700 mg / ml of the ethanol extract of the bark of Tynanthus panurensis, for Staphylococcus aureus was witnessed inhibition halos of 7 mm, 9 mm and 11 mm respectively, while for Escherichia coli and Pseudomonas aeruginosa, no halo of inhibition was observed at the mentioned concentrations, classifying them as resistant; in the Macrodilution method, for Staphylococcus aureus a Minimum Inhibitory Concentration (MIC) was found in the concentration of 32 mg / ml of the ethanolic extract, while for Escherichia coli and Pseudomonas aeruginosa, no one was found (MIC). It is concluded according to the interpretation of the results that the bacteria used are resistant to the ethanolic extract of the bark of Tynanthus panurensis (Clavo Huasca), therefore, it does not present antibacterial activity at the concentrations evaluated.
