Leaves, stem, roots and inflorescence of Solonum torvum Sw. were extracted in two different organic solvents (chloroform & methanol). Antibacterial and antifungal effects of the extracts were tested on fifteen (six Gram positive & nine Gram negative) human pathogenic bacteria and on eight pathogenic fungi. Methanolic extracts of roots of S. torvum exhibited promising antibacterial and antifungal effects on all organisms tested in comparison with that observed in the leaves, stems and inflorescence extracts. The toxicity of the extracts was in the following order; root>stem>inflorescence>leaf. The minimum inhibitory concentration (MIC) values of methanolic extract of roots of S. torvum were in the range between 64-128 mu g mL(-1). Chloroform extracts of roots were more toxic (LC(50) 35.4629 ppm) than other extracts analyzed in Brine shrimp test. In conclusion, S. torvum appears to be an attractive material for the development of antimicrobial drugs and environment friendly biopesticides.
