Abstract:
The antimicrobial activities of the aqueous fresh bark
extracts of Boswellia dalziellii, Ficus sycomorus and the
leaves extracts of Pseudocedrela kotschyi were
investigated against Ecsherichia coli, Staphylococcus
aureus,Staphylococcus species, Shigella dysenteriae,
Bacillus subtilis, Shigella sonnei, Salmonella typhi,
Pseudomonas aeruginosa, Aspergillus fumigatus,
Penicillium, Scopulariopsis species, Candida albicans and
Aspergillus niger. The leaves extract of Ficus sycomorus
exhibited antibacterial activity against Salmonella typi only
while there was antifungal activity against Aspergillus niger,
Aspergillus fumigatus and Penicillium comparable to
control. The water extract of the bark of Boswellia dazielli
had an inhibitory effect against the bacterial isolates with
the exception of Pseudomonas aeruginosa ,Salmonella typi
and Staphylococcus species. There was however no
detectable antifungal activity at the concentrations
employed. The crude leaves extracts of Pseudocedrela
kotschyi exhibited antifungal activities against the fungal
isolates with the exception of Candida albicans and
Penicillium; but show antibacterial activities against Staphylococcus aureus, Escherichia coli and Salmonella
typhi. These results confirm the earlier claim by herbal
practitioner that these plants possess antimicrobial activity.
