Abstract

Hannoa klaineana is an ever green plant belonging to the Simaroubaceae family commonly known as Oghuru in Igbo, itekiri in Edo and igi gun in Yoruba. It has been used in ethnomedicine for the treatment of malaria, cough, and stomach problems. The present study assessed the antimicrobial property of the extract of H. klaineana against Staphylococcus aureus, Salmonella typhi, Escherichia coli, Pseudomonas aeruginosa, Bacilus substilus, and Candida albicans using the agar diffusion method. Our preliminary phytochemical studies showed the presence of resins, steroids, terpenoids, glycosides, alkaloids, flavonoids, tannins, saponins, and phenols. Quantitative determination of the phytochemicals present revealed alkaloids (1.2%), tannins (11.2%), flavonoids (3%), saponins (29.3%), and phenolic compounds (45.7%). The extract of H. klaineana showed good antimicrobial activity against C. albicans and moderate active against S. aureus, S. typhi, E. coli, P. aeruginosa, B. substilus. These results further confirm the potentials of Nigerian plants as a source of bioactive compounds with pharmaceutical, agricultural or industrial applications.
