【 摘 要 】
The antibacterial activity of the extracts of Acacia longifolia (Andr.) Willd. leaves was evaluated by the gel diffusion method. The extracts were incorporated in paper discs and it was verified the effect on the human pathogenic bacteria growth. The tested bacteria were Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 11129) and Pseudomonas aeruginosa (ATCC 9027). The crude ethanolic extract, the ethyl acetate and the remained ethanolic fractions showed growth inhibition of S. aureus, only the crude ethanilic extract showed, in lower extension, growth inhibition of P. aeruginosa and no growth inhibition at all of E. coli. The phytochemical screening indicated the presence of tannins, leucoanthocianidins, flavonoids and triterpene/steroids.
