    Escherichia coli is one of the most common bacteria causing urinary tract infections and foodborne diseases, the incidence of this bacterium has caused a high rate of resistance to drugs. Baccharis salicifolia and Mansoa alliacea are medicinal plants with important pharmacological actions such as anti-inflammatory, antimicrobial, antipyretic and anticancer, used mainly by the indigenous and Shuar population of Ecuador. The present investigation had the objective of establishing the antimicrobial activity of these medicinal plants in Escherichia coli. The methods used to obtain the extracts were maceration in ethanol and decoction. To evaluate the antimicrobial activity, the logarithmic phase of Escherichia coli was determined, the minimum inhibitory concentration (MIC) was evaluated by means of 600nm readings correlated with the microbial viability of the Bromide 3- (4,5-dimethylthiazole-2-) test. ilo) -2,5-diphenyltetrazole (MTT) and checked on Mueller Hinton agar. The statistical analysis was performed by ANOVA; obtaining as a result that the extract of Baccharis salicifolia presented a CIM 16.2, 8.1 and 4.1g / mL while Mansoa alliacea showed a CIM 14.2 and 7.1g / mL. According to the findings of this study, it can be considered that Baccharis salicifolia and Mansoa alliacea contain active ingredients that act as antimicrobial agents
