ABSTRACT

Daniella oliveri powderd plant materials was extracted using methanol and sterile distilled water. The Agar diffused methods was used to determine the antimicrobial activity of the plant against Salmonella typhi, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli.  The methanolic and water both provide higher yield from different parts of the plant and both showed effectiveness except against Pseudomonas aureginosa. Phytochemical screening of the crude extract revealed the presence of tannins, saponins, phenolcs, flavonoids, cardiac glycosides, anthroquinones, and alkaloids and the growth of all bacteria were inhibited though to varying degrees thus justifying their use in traditional medicines in treating enteric infection and other diseases across Africa.

Key words: Daniella oliveri,  Phytochemicals, methanolic extract, Enteric infections.
