A COMPARATIVE STUDY OF DIFFERENT PARTS OF PSORALEA CORYLIFOLIA OBTAINED IN DIFFERENT SOLVENT EXTRACTS AGAINST PATHOGENIC BACTERIAP. TIWARIAbstract Medicinal plants are the local heritage with global importance and world is endowed with a rich wealth of medicinal plants. Plants have a great potential to be effective against the growth of pathogenic bacteria. In the present investigation, a comparative study is performed using different parts (seeds, tender stem and leaf) of Psoralea corylifolia obtained in different solvent extracts (methanol, petroleum ether and aqueous) against pathogenic bacteria ( Proteus vulgaris, Salmonella typhi, Kleibsella pneumonia and Pseudomonas aeruginosa). The antibacterial activity of these extracts was done against bacteria by agar disc diffusion method. Among the three extracts of various plant parts, methanol extract of leaf showed maximum inhibition against Salmonella typhi followed by Pseudomonas aeruginosa. The findings also suggest that methanol extracts of tender stem of Psoralea corylifolia also show great effectivity against bacterial infections.
