Comparison of the antimicrobial activity of two different extracts of Jordanian plants: a preliminary study

Aqueous and ethanolic extracts of three Jordanian plants [Rosmarinus officinalis, Mentha arvensis and Thymus capitatus] were studied for their antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, C and ida albicans, C and ida tropicalis and Trichosporon cutaneum. The antimicrobial activity was detected using filter paper disc diffusion method. The ethanolic extract of R. officinalis and T. capitatus inhibited the growth of all microorganisms used, while their aqueous extracts were active against S. aureus, B. subtilis and E. coli. Aqueous and ethanolic extracts of arvensis inhibited the growth of S. aureus, B. subtilis and E. coli
