The antibacterial and antifungal activities of some Moroccan medicinal plants extracts were evaluated against six bacterial species and three yeasts.

The agar diffusion method was used to evaluate the antimicrobial activity of the extracts of the following medicinal plants: Rosmarinus officinalis, Salvia officinalis, Psidium guajava, Crocus sativus, Dysphania ambrosioides, Trigonella foenum graecum and Cymbopogon citratus. The used standard antibiotic is the Ampicillin 30µg, and the standard antifungal is the Econazole30µg.

The highest antibacterial activity was observed for the extracts of Rosmarinus offficinalis (16,6mm

This study proves, in part, that excepted Dysphania ambrosioides all the studied medicinal plants  extracts have a good antibacterial activity, so they can establish a source of alternative antibiotics in the  pharmaceutical industry. On the other hand,  the species of these studied medicinal plants  could be valuable due to their bioactive compounds. The results confirm also the ethnobotanical importance of the screened plants for the treatment of some bacterial infections.
