The present study was carried out to investigate possible antibacterial; antioxidant activities and phytochemical screening of ethanol extract some Sudanese medicinal plants. Phytochemical analysis of the crude extract was performed to detect presence of different kinds of phytoconstituents. The antibacterial activity was investigated against two Gram positive and two Gram negative bacteria and two fungi by using disc diffusion method. All extracts showed moderate or week antimicrobial activity against all strains used except M. pigra extract, which showed promising activity. Antioxidant activity showed that M. pigra was the most active one (85±0.05) compare to the other sample and standard propyl gate (83±0.05). Pytochemical screening showed the presences and absence of the secondary metabolites among all sample tested.
