Abstract
All over the world, specifically in rural areas of developing countries, people use traditional medicines for curing numerous diseases. Medicinal plants are widely used in the field of ethnomedicine for various ailments. Plant derived medicinal products are being used in ethnomedicinal system from times unknown and have been recorded in many pharmacopoeia as antimicrobial agents. In the present study two ethnomedicinally important plants i.e. Lawsonia inermis and Adhatoda vasica were evaluated for their antimicrobial potential against some pathogenic bacteria viz. E. coli, Enterobacter aerogenes, Salmonella typhi and Agrobacterium tumefaciens. Different plant parts were examined using Water, Ethanol, Chloroform, Acetone and Petroleum ether as solvents. The antibacterial activity was determined by using Disc Diffusion method. Ciprofloxacin was used as positive control whereas DMSO and water as negative controls. Significant antibacterial activity was observed in most of the plant extracts evaluated. In case of Lawsonia inermis the highest antibacterial potential was exhibited by Petroleum ether extracts of leaves against E. coli whereas acetone extract of flowers of Adhatoda vasica were found highly effective against E. aerogenes. The phytochemical analysis revealed the presence of alkaloids, glycosides, tannins, saponins, phenols, steroids and flavonoids. The findings of present study indicate that the plant extracts evaluated can prove to be potential antimicrobial agents against disease causing pathogenic bacteria.
