Abstract
The aim of this study was to evaluate the biological activity of organic solvent extracts of Euphorbia prostrate on growth inhibition of Pseudomonas aeruginosa and Staphylococcus aureus and compare them with several antibiotics. The results of testing alcohol extracts showed high efficiency in inhibition of growth of S. aureus in concentration of 50mg/ml , but for P. aeruginosa , growth inhibition began at 70mg/ml. Results also showed that hexane extract had no effect on both bacteria. on the other hand, Ethyl acetate extract had inhibitive effects on S. aureus at 70mg/ml and on P. aeruginosa at 90mg/ml. When the activity of the three organic extracts on inhibition of test bacteria were compared with several antibiotics, identity of inhibition degree was found between them and even superiority on some others
