Antibacterial activity of crude extracts of Butea monosperm

Abstract

Crude extracts of different parts (flowers and roots) of Butea monosperma were examined for their  antibacterial activity against four bacteria viz. Bacillus megatarium, Bacillus subtilis, Escherichia coli, Pseudomonas aeuroginosa. Antibacterial activity of different plant parts in terms of Minimal Bactericidal Concentration [MBC] (µg/mL) ranged between 0.1-­‐100 µg/mL. The extracts performed as good as or even better than the standard drugs like Ampicillin, Chloramphenicol and Ciprofloxacin. Highest antibacterial activity is observed for flower extract. The flower extract          is found to be the most effective against Escherichia coli and root extract is recorded against Bacillus subtilis.
