The antibacterial activity of the flowers of Acacia podalyriifolia A. Cunn. (Leguminosae) was evaluated through the gel diffusion method. The bacteria tested were: Staphylococcus aureus (ATCC 6538), Staphylococcus epidermidis (ATCC 1228), Escherichia coli (ATCC 11229) and Pseudomonas aeruginosa (ATCC 27853). The culture media was agar Müeller-Hinton. Paper discs (6 mm in diameter) with 1000, 500, 250 e 125 mg of the tested extracts (crude ethanolic and its fractions; Ethyl Acetate and Dichloromethane) were used. The results indicated action against the gram-positive tested strains in different levels. The Ethyl Acetate extract showed a higher activity. Phenols and flavonoids were detected in the flowers of A. podalyriifolia through phytochemical screening.
