In vitro study on antimicrobial efficacy of Rumex nervosus L. extracts on Staphylococcus aureus , Escherichia coli, and Candida albicans

Abstract

Rumex nervosus L. (Polygonaceae) crude extracts were evaluated for antibacterial and antifungal activities . Methanolic and aqueous crude extracts of seeds and leaves were prepared. The tested microorganisms were clinical isolates of Escherichia coli (G-), Staphylococcus aureus (G+), and Candida albicans, The antimicrobial effects were detected by total colonies count and by using well diffusion method. Methanol and water leaves extracts showed a notable effects on the three microbes , while seeds extractions showed low affectivities. Methanol extraction also had more effective than aqueous one,The results showed that E.coli isolates are more sensitive to the crude extracts than S.aureus.
