The present study focuses on the antibacterial and
antifungal activity of the medicinal plant Aristolochia
bracteolata. Aqueous, methanol and chloroform extracts
of this plant were evaluated against the bacterial strains
Escherichia coli, Bacillus subtilis,
Staphylococcus aureus, Klebsiella pneumoniae,
Pseudomonas fluorescens, Shigella flexneri,
Proteus vulgaris and the fungal strains like
Aspergillus niger, Aspergillus terreus, Penicillium notatum
and Rhizopus stolonifer. Among the three extracts
assessed, methanol extract was found to have the significant
activity followed by the chloroform extract against certain
bacteria. Water extract did not have any activity against
bacteria. Antifungal activity assessment indicated that the
tested fungal strains are more susceptible to aqueous
extract followed by methanol extract and chloroform extract.
Key words:
Antibacterial, antifungal, Aristolochia bracteata,
minimum inhibitory concentration. |
