Stryphnodendron obovatum Benth., popularly known as "barbatimão", belongs to the Leguminosae fami/y, of the Mimosoideae subfamily, and is present in fields and in "cerrados". S. obovatum bark is used in popular medicine for treating inflammatory processes, for healing wounds, and as cure for diarrhea and chílblain. This research investigates the presence of proteins and the cytotoxic, antifungal, antibacterial and antioxidant activities of the S. obovatum seed saline extract. The saline extract did not show cytotoxicity against Artemia salina nor any antibacterial activíty against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia colí. The evaluation of the antioxidant activity showed a CEso=12.193 µg/mL, and the BHT positive pattern presented 2.98 µg/mL. The S. obovatum saline extract was tested against Cladosporium sphaerospermum and Candida albicans, using the bioautography technique and the disk diffusion method. Benzoylarginine-p-nitroanilide (Bz-Arg-pNan) was hydrolyzed by the saline extract.
