Objective: To determine whether there is antibacterial activity of coca leaf extract (Erythroxylum coca), on black pigmented bacilli (BPB). Materials and method: Two tests were used: Diffusion Test in Agar and Dilution in liquid medium. The BPB strains were isolated from samples taken from periodontal pockets of patients with periodontal disease treated at the Faculty of Dentistry of the Mayor National University of San Marcos. The hydroalcoholic extract of coca leaf was obtained from the National Company of Coca (ENACO). Results: The first agar diffusion test indicated null sensitivity (-) for most of the concentrations evaluated, and limit sensitivity (sensitivity: +) for the concentrations of 12.5% and 100%. The results of the dilution sensitivity determined a minimum concentration of the extract capable of inhibiting the growth of this bacterium, 100% (minimum inhibitory concentration), and at the concentrations of 12.5% and 6.25% a repotentiation of the antibacterial effect of the extract. Conclusions: The hydroalcoholic extract of coca leaf, does present an antibacterial activity against BPB, at concentrations of 100% and 12.5%.Downloads
