The members of the Frankeniaceae family are distributed in an only genus, “Frankenia”. F. triandra grows in extreme regions of high UV radiation in the Argentine Puna. The aim of the present work was to make a preliminary phytochemistry analysis and evaluation of biological activities of extracts obtained from aerial parts of F. triandra by different methods of extraction.Three extractions were made: alcoholic, aqueous and hydroalcoholic. The total phenolic compounds and flavonoid content were determined by spectrophotometric methods. Scavenging capacity of ABTS+ cation radical was determined by autographic methods.  The minimal inhibitory concentration of the extract against antibiotic-resistant human pathogenic microorganisms was determined by macrodilution method. All extracts has showed free radical scavenging activity and only the alcoholic and hydroalcoholic extracts presented antibacterial activity. A selective inhibitory effect against Staphylococcus aureus was observed. The results indicate that F. triandra could be used in cutaneous infection and to aliviate the oxidative stress.
