Abstract

Plants being an invaluable source of the natural products help to sustain the human’s well being. They are the alternatives for the production of chemical- therapeutic agents. A wide diversity of medicinal plants plays an important role for the repository of antimicrobial agents. Since time immemorial, scholars have been using various means and modes to identify, screen and extract the antimicrobial substances present in plants. The present investigation is an attempt to evaluate the antimicrobial nature of the selected plant. The plant derived extracts with selective solvents were tested against eight microorganisms of significant importance. Antimicrobial assay was performed using agar disc diffusion method. The plant samples viz. bark, stem and leaves were found to display varying inhibition zones against the selected microbes. Extracts derived with organic solvents were more potent than aqueous extracts. Methanol derived extracts were most effective followed by acetone and petroleum ether. The effectively of various plant extracts were found to be more as compared to standard antibiotics Streptomycin and Ketoconazole. The consequential findings were later used to validate the usage of the plant in the field of pharmaceuticals and therapeutics.
