Antibacterial and Antifungal Activity of Colocasia esculenta Aqueous Extract: An Edible Plant
Journal Title: Journal of Pharmacy Research - Year 2011, Vol 4, Issue 5
Abstract
The in-vitro antimicrobial activity in aqueous extract of Colocasia esculenta (AECE) leaves were studied against gram positive bacterial strains i.e. Streptococcus mutans (MTCC-890), Bacillus subtillis (MTCC-121), gram negative bacterial strains i.e Klebsiella pneumoniae (MTCC-109), Pseudomonas fragi ( MTCC-2458), Escherichia coli (MTCC-483) and fungal strains Aspergillus niger (MTCC-281) Candida albicans (MTCC-227). The antimicrobial activity of AECE was determined by agar well diffusion methods at the concentrations ranging from 100-500μg /ml. Standard antibiotic discs were used as positive controls. AECE gave maximum activity against Streptococcus mutans amongst the selected microbial strains. In conclusion, the Colocasia esculenta extract exhibited good antimicrobial activity against some of tested bacteria and fungus at low concentration. The results provide promising information for the potential use of Colocasia esculenta aqueous extract in the treatment of infection.
