الملخص EN

Aqueous and alcoholic extracts of law Sonia inermis were tested for their antimicrobial activity; four types of bacteria were selected these are Staphylococcus aureus ; Escherichia coli ; Enterococcus faecalis and Pseudomonas aureginosa Minimal Inhibitory Concentration(MIC) were determined for both aqueous and alcoholic extracts ; the aqueous extracts was more potent than alcoholic extract regarding MIC 8-64 mg / ml and 32-64 mg / ml for aqueous and alcoholic extracts respectively .All the selected bacteria showed clear sensitivity for those extracts except the Escherichia coli showed more and greater.

The results revealed that aqueous extract of law Sonia inermis is more potent than alcoholic extract in their antibacterial activity and produced bacteriostatic effects so in this study we recommended the use of this plant for superficial skin infections caused by S.

aureus ; P.aeruginosa and E.

faecalis.
