Antibacterial Activity of Hydrodistilled Essential Oil of Psammogeton canescens N.O. Umbelliferae

Mujeeb ur Rahman and Shereen Gul

Abstract: The essential oil of Psammogeton canescens obtained by hydro distillation was evaluated for its antibacterial activity against gram positive (Bacillus megaterium, B. subtilis, Lactobacillus acidophilus, Micrococcus leuteus, Staphylococcus albus, S. aureus, Vibrio cholera) and gram negative bacteria (E. coli, Salmonella typhae, Shigella ferrarie). The oil was found active against all the bacterial strains. However the activity of oil varies with its concentration and kind of bacteria. The oil showed activity even at 50μg concentration. The antibacterial activity was comparable with amoxil, streptomycin and kanamycin. The oil had bactericidal activity against all the bacteria under investigation except Shigella ferrarie, Micrococcus leuteus and Vibrio cholera. The MIC value of oil varies from 75.5-160 and 75.5-135mg ml⁻¹ against gram positive and gram negative bacteria, respectively.
