In recent years this interest to evaluate the properties and uses of medicinal plants are getting growing interests now. Plants possessing antibacterial activity for various diseases are being studied by various methods to evaluate their antibacterial property. Different solvent extracts (aqueous, alcohol and ethanol) of leaves, flower and seeds of various plants were subjected to in vitro antibacterial activity assay against gram-positive and Gram-negative bacteria employing different diffusion method. Based on common use and ethno botanical knowledge, an attempt has been made to assess the the antibacterial properties of selected medicinal plants viz. Azadirachta indica, Allium sativum, Holarrhena antidysenterica and more for potential antibacterial activity against some important bacterial strains, namely Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Salmonella Typhi, Escherichia coli and Klebsiella pneumonia.
