Abstract

ABSTRACT Antimicrobial activity of solvent extracts of Brassica nigra, Trigonella foenum-graecum, and Schinus molle were investigated against six bacterial pathogens. The highest zone of inhibition (ZOI) were noted for methanol extract of B. nigra against S. boydii. The highest activity index (AI) was noted in methanol extract of B. nigra against S. boydi (AI = 0.86) using ciprofloxacin as positive control but AI ≥ 1.0 in some extracts while using gentamicin as positive control. The minimum inhibitory concentration (MIC) of the extracts ranged from 6.25 mg mL−1 to 100 mg mL−1. The antibacterial activity of the extracts was B. nigra > T. foenum-graecum > S. molle.
