Author(s):

Abstract:
In the present study different fractions from ethanol extracts of Couroupita guianensis and Atalantia monophylla were isolated and tested for their antibacterial bioassay on selected pathogens. Antibacterial activity was determined against three gram positive bacteria Staphylococcus aureus, Streptococcus epidermidis, Bacillus subtilius and four Gram negative bacteria Escherichia coli,Pseudomonas aeruginosa, Salmonella typhi, Vibrio cholerae, Proteus vulgaris was carried in well diffusion method. The results obtained fractions from ethanol crude extracts of Couroupita guianensis and Atalantia monophylla had inhibitory effect on the growth of isolates. The effect exhibited by ethanolic extract fractions was significantly greater than the fraction II and fraction III. Gram negative bacteria Escherichia coli and the Gram positive bacteria Staphylococcus aureus showed the highest zone of inhibition in ethanol extracts fractions II and III of Couroupita guianensis and Atalantia monophylla.
