The present investigation focused on the toxicological efficacy of essential oil of Murraya koenigii (L.). The oil was extracted from the leaves using the hydro-distillation method. Further, its toxicological efficacy was evaluated against Escherichia coli (MTCC-723), Klebsiella pneumoniae (MTCC-4032), Salmonella typhimurium (MTCC-3231), and Vibrio cholerae (MTCC-3906). The toxicological efficacy of the essential oil was found to be highest against S. typhimurium. Inhibitory activity was also observed against K. pneumoniae and E. coli (MTCC-723). The least activity was recorded against V. cholerae. Hence, the essential oil from the leaves of M. koenigii exhibits great potential for the development of eco-friendly, non-toxic, cost-effective antibacterial herbal drug formulations.
