The objective was to determine the in vitro antibacterial activity of ethanol extract of leaves of Jatropha gossypifolia L "black gear" by macrodilution method. The leaves of the species was collected in the study of Faculty of Agronomy in Zungarococha, San Juan Bautista, Iquitos, and was identified in the Herbarium Amazonense (UNAP) was collected. The leaves were stored in the pilot of the Faculty of Food Industry UNAP plant, once dry ethanolic extract by maceration at room temperature was prepared and then the solvent was evaporated to a dry extract. To study the in vitro antibacterial activity Staphylococcus aureus ATCC 25923 as Gram positive and Escherichia coli ATCC 25922 was used as Gram negative. The results of Minimum Inhibitory Concentration of the ethanol extract of leaves of Jatropha gossypifolia L was 8 mg / ml for Staphylococcus aureus ATCC 25923 and 16 mg / mL for Escherichia coli ATCC 25922 it is concluded that the evaluated extract resulted inactive in inhibiting the development of the reference strain E. coli. and some activity against Staphylococcus aureus.
