Nizar Sirag, Elhadi M M Ahmed, Anwar Mohammed, Mohamed Abubakr


The present study was undertaken to investigate the antibacterial activity and to find the biologically active functional groups of four medicinal plants. The ethanolic extracts which were obtained by maceration were tested against in vitro five bacterial strains, using cup-plate agar diffusion method. Preliminary phytochemical screening techniques were also used to test for the presence and nature of the active constituents in these plant extracts.
