The anti-inflammatory, antibacterial and mutagenic effects of the aqueous extract of Amburana cearensis seeds were evaluated. The anti-inflammatory activity was evaluated by a paw edema model induced by carrageenan, using the extract at 10 % and 20 % concentrations in the experimental groups: AAS 10 mg/kg (orally administrated) in the standard group and distilled water in the control group. The antimicrobial activity was determined by the agar dilution method, using extract concentrations of 10 %, 7.5 %, 5 %, 2.5 % and 1% in strains of Staphylococcus aureus ATCC 27853, Escherichia coli ATCC 25922 and Pseudomonas aeruginosas ATCC 25923), and the mutagenic activity was determined by the Allium cepa test using extract concentrations of 0,02 mg/mL, 0,1 mg/mL and 0,5 mg/mL. The aqueous extract of Amburana cearensis seeds at 10 % and 20 % concentrations had an statistically significant antiedematogenic effect two hours after administering the flogogen, and this effect persisted for up to 24 hours after inducing the inflammatory response. Regarding the antibacterial activity, the extract showed no action against the bacterial strains of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosas at the concentrations tested. The results of the Allium cepa test showed the toxic (at a concentration of 0,5 mg/mL) and mutagenicity (0.1 mg/mL micronucleus and 0.1 mg/mL and 0.5 mg/mL chromosomal aberrations) actions of the Amburana cearensis extract on meristematic cells of Allium cepa. These results suggest potential therapeutic applications to treat inflammations. However, they also show the need for further studies to demonstrate the safe use of this species.
