ABSTRACT
Antimicrobial activity of ethanolic extract of Mangifera indica peel was
tested on some pathogenic organisms. The extract was tested for activity
against, Baciollus subtilis, Staphylococcus aureus, Escherichia coli, Salmonela
typhii, Pseudomonas notatum and Aspergillus fumigates. The extract exhibited
activity against the organisms in varying degrees. In agar diffusion test,
Escherichia coli showed the highest zone of inhibition (8mm) at the
concentration of the extract test (1g/3ml) while Staphylococcus aureus,
Salmonella typhii, and Bacillus subtilis showed zone of inhibition of 5mm, 6mm,
and 2mm respectively while Aspergillus fumigates and Pseudomonas notatum showed
not zone of inhibition. At 1g/ml concentration Escherichia coli showed zone of
14mm, while Staphylococcus aureus, Salmonella typhii, Bacillus subtilis showed
zone of inhibition of 10mm, 13mm, 8mm, respectively. The result reveals at
varied concentration, the extract did not have any activity against the fungi
used.
