Abstract:

The present work embodies the antimicrobial activities of some flora of Mt. Linayan in Mt. Province. The plant specimens chosen were Azolla filiculoides and Brachythecium buchananii. The ethanolic extracts of these plants were screened for their microbiological, pharmacological and toxicological activities against Escherichia coli, Staphylococcus aureus, Fusarium oxysporum and Tricophyton mentagrophytes. The mean inhibition zones of the ethanolic extracts of Azolla and B. buchananii proved that these plants were found to be active against the fungi but inactive against bacteria. The Patch and Scratch Tests employed showed very minimal erythema and edema among test organisms. These findings suggest a high potential of antimicrobial activities in the plant specimens.
