Although the Acacia genus (Fabaceae) is represented by more than 1350 species distributed worldwide, there are few reports on the chemical composition and biological properties of Argentinean Acacia species. The presence of different flavonoids in the leaves and stems has been reported. Acacia aroma is the most widely studied species in this genus. Antioxidant, anti-inflammatory and antimicrobial activity against multi-resistant human pathogenic bacteria have been reported for A.aroma. In this work we present the study of the phytochemical and biological (antioxidant and antibacterial activity) screening from four Argentinean Acacia species extracts (Acacia aroma, Acacia caven, Acacia visco, Acacia praecox). Phytochemical screening showed similar chemical patterns by TLC for A. aroma and A. visco The presence of alkaloids was discarded. TLC-autography (DPPH/ABTS) and bioautography assay against Staphylococcus aureus methicillin-resistant were performed. Antioxidant and antibacterial activities were demonstrated in all preparations.
