In-Vitro Anti-Bacterial Activities of Three Medicinal Plants Using Agar Well Diffusion Method

Medicinal plants play a vital role for health care. The constituents of medicinal plants control the h yperglycemia as well as its secondary complications. The purpose of this st udy was to evaluate the antibacterial activity of m edicinal plants by agar well diffusion assay. Three medicinal plants ( Saussurea lappa , Ricinus communis and Acacia nilotica ) were used against four bacterial strains ( Lactobacillus subtilis, Bacillus thureogenesis, Cor ney bacterium and Escherichia coli ). These three medicinal plants were macerated into three forms (E thanol, Chloroform and Simple macerated extracts). Then, with the help of agar diffusion assay the antibacterial acti vity of these medicinal plants were measured. The z ones of inhibition were measured with the help of scale and they were repre sented by graphs and tables. These medicinal plants showed antibacterial activity against four available bacte rial strains. The present study suggests that the e thanol extracts of these medicinal plants contain compounds that can form th e basis for the development of a novel broad spectr um antibacterial formulation.
