--- The use of plants to relieve infections successfully leads us to investigate their activities and make formulations taking advantage of the active ingredients present. Is thus; in this study the antimicrobial effect of the gel made from ethanol extract of leaves of Senecio rhizomatus Rusby, selected based on ethnopharmacy and ethnobotany. It was collected in the area of Chavin de Huantar, Huari district, Department of Ancash, the common name of this species is “Llancahuasha“, which it was made an ethanolic extract of leaves for determination of secondary metabolites using tube reactions and Thin Layer Chromatography for determination of alkaloids. With ethanolic extract, it is elaborated an antimicrobial gel at concentrations of 12,5 and 25 mg/mL ; Its antimicrobial effect was evaluated by the agar well diffusion method, using strains of Staphylococcus aureus isolated from hospital clinic and community samples. It was found alkaloids, flavonoids and steroidal saponins by reading and interpretating of clear zones of inhibition of bacterial growth, it was found significant antibacterial effect of the gel to a concentration of 25 mg/mL versus community strain of S. aureus, halo inhibition formed was 20 mm and hospital strain, with the inhibition halo formed was 18 mm. It is concluded that the gel made from ethanol extract of leaves of Senecio rhizomatus Rusby has antibacteril effect in vitro. Keywords: Senecio rhizomatus, antimicrobial gel, agar well diffusion, Staphylococcus aureus, inhibition
