The present investigation focused on the qualitative analysis of components of essential oil using GC-MS and antibacterial efficacy of essential oil of Juniperus communis L. The oils were extracted from the leaves using hydro-distillation method. The antibacterial activity of the extracted essential oils was evaluated against Escherichia coli (MTCC No. 723), Klebsiella pneumoniae (MTCC No. 4032) and Salmonella typhimurium (MTCC No. 3231) using Kirby-Bauer disc diffusion method recommended by Clinical Laboratory Standard Institute (CLSI) formerly (NCCLS). Nineteen different compounds have been identified. Essential oil activity was found most effective against S. typhimurium whereas found least effective against K. pneumoniae. Hence, essential oil from leaves of J. communis exhibit great potential for the development of eco-friendly, non-toxic, cost-effective anti-bacterial formulations.
