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.
