Evaluate the antimicrobial activity of Boswellia carterii (frankincense), Glycyrrhiza glabra (Licorice) and Rosmarinus officinalis (Rosemary) against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and klebsiella pneumoniae. The extracts were prepared using soxhlet apparatus for 8 hours. Evaluation of antimicrobial activity was carried out using disc diffusion method and Minimum inhibition concentration method (MIC) at different concentrations for (200mg/ml -0.39mg/ml) for all tested bacteria. The results of this study showed that the D.W, ethanol and chloroform extracts of rosemary showed the lowest minimum inhibitory concentration against S. aureus and all extracts of licorice against K. pneumonia. However, extracts of frankincense showed a broad change in values from (12.5mg/ml) to (50mg/ml). These results illustrate the importance of tested the plant extracts against pathogenic organisms as the first step in the path to further encourage the use of natural extracts as alternative method to chemical treatment.
