Chemical composition, GC and GC-MS analysis and in vitro antibacterial activity of the essential oils of the aerial parts of Satureja parvifolia (Phil.) Epling collected in San Juan Province Argentine were performed. Twenty six compounds were identified accounting for 94.1% (area %) of the essential oil. The major constituents were piperitone (34.9%), piperitenone (27.3%), cis-piperitenone epoxide (15.0%) and piperitenone oxide (6.0%). The in vitro antimicrobial activity of the essential oil was investigated by the microdilution method, with Cefotaxime as the standard antibiotic against seven Gram-negative and three Gram-positive bacteria. A strongest activity was observed for the essential oil against all Gram negative bacteria assayed, principally Yersinia enterocolítica-PI and Salmonella enteritidis-MI with a MIC value equal to 0.82 mg/ml.
