Abstract
The leaves and twigs of Viscum album L. (Family: Loranthaceae) were extracted successively with various organic solvents and water. These crude extracts were assessed for antimicrobial activities against three Gram positive bacteria, five Gram negative bacteria, one yeast and one fungus by using disc diffusion method. The Ethylacetate, chloroform, ethanol, and methanol crude extracts of selected plant parts had significant antimicrobial activities on both Gram positive and Gram negative bacteria. The Ethylacetate and methanol crude extracts of leaves and twigs of Viscum album exhibited prominent activities against Gram positive and Gram negative bacteria used in comparison to other extracts which had moderate activity against all the tested bacteria. The antimicrobial activities of the crude extracts of the selected plant parts were more active against Gram negative bacteria than Gram positive bacteria. The standard reference antibiotics, Ciprofloxacin (100 mu m/ml) and Nystatin (1500u/ml) were used as positive control.
