Abstract
For many years medicinal plants have become a research interest and focus especially for providing primary healthcare needs. This study was carried out to determine the phytochemical properties as well as the antibacterial activities of methanol and ethanol extracts of the dried roots of Anthocleista djalonensis. The whole dried roots specimen of Anthocleista djalonensis was extracted using soxhlet extraction apparatus. These extracts were further screened for antibacterial activity using agar well diffusion technique. Twelve clinical and typed strains of bacteria isolates were tested for susceptibility to these extracts. The bacteria strains used were; Bacillus cereus (NLCC 14724), Bacillus cereus (NLCC 14725),Staphylococcus aureus, typed Staphylococcus aureus, Salmonella typhi, typed Salmonella typhi, Escherichia coli, typed Escherichia coli, Psedomonas aeruginosa, typed Psedomonas aeruginosa, Bacillus subtilis, Proteus mirabilis.
However, both extracts had significant antimicrobial activity (p<0.05) on ten out of the twelve isolates which includes Bacillus cereus (NLCC 14724), Bacillus cereus (NLCC 14725), Staphylococcus aureus, Salmonella typhi, typed, Escherichia coli, typed Escherichia coli, Psedomonas aeruginosa, typed Psedomonas aeruginosa, Bacillus subtilis, Proteus mirabilis. The typed strains of Staphylococcus aureus and Salmonella typhi were not susceptible to any of the extracts.
Meanwhile, the phytochemical analysis revealed the presence of tannin, saponin, reducing sugar, alkaloid, flavonoid and glycosides. These compounds have been found to be responsible for the antibacterial activity of the extracts.
