Abstract

Extract of organic solvent (Aqueous, methanol and acetone) of medicinal plant Chenopodium album L. were evaluated for their antimicrobial activity against Gram positive bacteria (Staphylococcus aureus, Bacillus subtilis) and Gram negative bacteria (Escheichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa). These were carried out by taking organic extract of leaves of plants at concentration of 5mg/ml and their activities were recorded by estimating zones of inhibition as produced by Disc Diffusion method on nutrient broth. The acetone and aqueous extracts of leaves of various tetraploid plants also revealed no toxic or antibacterial activity. The methanol extract of leaves collected from the tetraploid plants of the species showed antibacterial activity against only two bacterial strains Klebsiella pneumoneae and Pseudomonas aeruginosa. For these Zone of Inhibition was estimated as 9.66-14.00 for Klebsiella pneumoneae and 10.66-13.66 for Pseudomonas aeruginosa.
