Inhibition zones were recorded between 9mm against Pseudomonas aeruginosa and 44mm against Staphylococcus aureus at concentration of 200mg/ml for the methanolic extract. Whereas the inhibition zones for the ethanolic extract were recorded between 7mm at concentration of 40mg/ml against Streptococcus sp. and 34mm at concentration of 200mg/ml against Staphylococcus aureus.
