Abstract


The antimicrobial activity of leaf extracts of four selected medicinal plants such as Phyllanthus amarus Schumach&Thonn, Senna auriculata(L.)Roxb. (?Cassia auriculata L), Phyllanthus maderaspatensis L, and Solanum torvum Sw. were studied against four microorganisms such as Pseudomonas aeruginosa, Pseudomonas fluorescens, Penicillium chrysogenum and Penicillium restrictum. A perusal of results on the antimicrobial effects of leaf extracts of the four plants (prepared in 4 different solvents) indicated that the magnitude of antimicrobial effects was higher in ME extracts followed by EA and CF whereas the least antimicrobial activity was observed in PE extract.
