Spathodea campanulata, anti-microbial activity, Staphylococcus aureus, E.coli


The antibacterial activity of methanol stem bark of Spathodea campanulata was investigated by testing the extracts against Escherichia coli, and Staphylococcus aureus. The minimum inhibitory concentration (MIC) of the methanol extract was determined against the two bacteria strains by using the disc diffusion method. Four different concentrations of S. campanulata such as (100 µl/ml, 200 µ/ml, 400 µl/ml) were prepared. After incubation for 24 hrs, the zone of inhibition was compared with standard antibiotics streptomycin (100 µg/ml).The present results revealed that the maximum zone of inhibition was observed in E.coli (mm) of 200 µg/ml concentration when compared to control. The result significantly paves the way for further application of Spathodea campanulata stem bark waste as antibacterial materials.
