Solanum nigrum is an important ingredient in traditional Indian medicines. In the present paper deals the level of larvicidal activity of ethanol, hexane and chloroform extracts of stem and leaf of Solanum nigrum at different concentrations viz., 500, 1000 and 1500 ppm has been investigated. The results obtained show that this plant material exhibited significant activity and could be considered as potent natural larvicidal agent. The antibacterial activities of ethanol, hexane and chloroform extracts of stem and leaf, Solanum nigrum were screened against various pathogenic bacteria by ‘agar well diffusion’ method. The plant extracts showed various levels of activity on different test organisms among that ethanol extract of Solanum nigrum stem was found to be the most potent extract.
