Abstract:-According to World Health Report of Infectious diseases 2000, overcoming antibiotic resistance is the major issue of the WHO for the next millennium. Hence the last decade witnessed an increase in the investigation of plants as a source of human disease management. The aim of the present study was to investigate antibacterial activity of the various extracts of Hibiscus sabdariffa and Solanum trilobatum. The powdered plant leaves materials were extracted in n-hexane, chloroform, ethyl acetate, ethanol and water and their antibacterial activities were examined against some collected clinical isolates using agar dilution method. The qualitative screening of phytochemical compounds of H. sabdariffa and S.trilobatum were performed. Ethanolic extract of Hibiscus sabdariffa and hexane extract of Solanum trilobatum gave the highest inhibition against all the urinary isolates. The presence of starch, proteins, aminoacids, steroids, cardiac glycosides, saponin glycosides, coumarin glycosides, flavanoids, tannins ,phenolic compounds and the presence of steroids, cardiac glycosides and coumarin glycosides, aminoacids and flavanoids were observed in the phytochemical screening of H. sabdariffa and S. trilobatum extracts respectively. These findings reveals that antimicrobial activity especially against the urinary pathogens of the selected plant extracts may be due to the presence of these phytochemicals. The spectra of activities displayed by the extract signifies the potency of Hibiscus sabdariffa and Solanum trilobatum as a source of therapeutic agents and may provide leads in the on going search for antimicrobial agent from plants.
