Abstract

In the present study the acetone, methanol, chloroform, ethanol and distilled water extracts of leaves from Brachychiton diversifolius R.Br were evaluated for their antibacterial activity against four clinical pathogens namely; Micrococcus luteus, Staphylococcus aureus, Acinetobacter baumannii and Pseudomonas aeruginosa. The inhibition zones (IZs) were ranged between 7-17 mm at a concentration of 2000 µg/mL. Methanol and ethanol extracts showed good activity against the growth of M. luteus (IZ value of 17 mm). Chloroform extract presented moderate activity against S. aureus (IZ value of 8 mm). The methanol extract presented good activity against A. baumannii (IZ value of 15 mm) followed by the chloroform extract (IZ value of 12 mm). Furthermore, the distilled water extract was showed a selectively active against the growth of P. aeruginosa with IZ value of 10 mm, while the other extracts did not show any activity. The present results could be promise a basis for further work related to the bioactivity agents from B. diversifolius against the growth of human bacterial pathogens.
