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.
