Antimicrobial properties of Berlina grandiflora Hutch. and Dalz. leaf extract were investigated against both clinical and laboratory isolates. Susceptibility of these isolates to the extract was determined using disc diffusion method. The antimicrobial screening had wide range of activity on Escherichia coli, Stapylococcus aureus and Streptococcus spp. The diameter of zone of inhibition by the extract was 7, 8.7 and 9 mm respectively. The minimum inhibitory concentrations (MIC) were 32.81, 19.38 and 11.72 µg/ml for E. coli, S. aureus and Streptococcus spp. Based on the current findings, it can be concluded that B. grandiflora has antimicrobial activity against certain microorganisms.


Key words: Berlina grandiflora, antimicrobial agent, minimum inhibition concentration, in vitro.
