ABSTRACT
Extracts of Anchomanes difformis (Blume) Engl. [family ARACEAE] was investigated for antimicrobial activity against Bacillus subtilis, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, Candida stellatoidea and Candida torulopsis using agar well diffusion methods and minimum inhibitory concentrations. All the bacteria tested were sensitive to the essential oils except for Pseudomonas aeruginosa that was only sensitive to the oils from the stem and root but not to that of leave. Virtually all the Candida species tested were resistant to the essential oils except for Candida torulopsis that was sensitive to the oil from stem. The minimum inhibitory concentrations ranged from 2.0mg/ml to 4.0mg/ml and were recorded for Bacillus subtilis, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus in the stem, root and leaf extracts. Conclusively it was observed that inhibition of selected bacteria and fungi by essential oils of Anchomanes difformis makes it a promising antimicrobial agent.
