Ruta chalapensis, Rumex nervosus, E. coli, S. aureus, Anti Microbial Activity, Phytochemical Screening
Background: Ruta chalapensis and Rumex nervosus are used as an extensive household remedy for various diseases in Eritrea. The components of these plants are of great interest in medicinal chemistry. Leaves and young stems of Ruta and Rumex have been reported to contain alkaloids, flavonoids, phenols, amino acids, furanocoumarins and saponins. Various solvents like ethanol, acetone and aqueous extracts of the two plants were screened for the presence of bioactive compounds.
Methods: The antibacterial activities of these extracts were investigated against Staphylococcus aureus, a gram positive bacteria and Escherichia coli, gram negative bacteria. The antibacterial activity was tested using Muller Hinton Agar medium by disc diffusion method and minimum inhibitory concentration assays.
Results: After incubation, zone of inhibition was measured in mm, a good inhibition (>5mm) was observed indicating the effective antibacterial activity of the bioactive compounds in both the plant extracts.
