This research was conducted to evaluate the components of the Mentha pulegium (L) and Glycyrrhiza foetida (Desf) that were extracted by hydro distillation and analyzed using GC-MS methods. They are spontaneous plants widespread in Gharb of Morocco. The aim of the study is to investigate the antibacterial activity of the essential oils and leaf methanolic extracts of these two medicinal plants against five phytopathogenic bacteria. The evaluation of the antimicrobial activity of the two species by estimating the diameter of the inhibition zone has shown that the essential oil of M. pulegium exhibited a higher antimicrobial activity than G. foetida which varied according to the sensitivity of the phytopathogenic strains. The results obtained revealed different degrees of sensitivity toward methnolic extract. However, the methanolic extract and the essential oil of M. pulegium are more active based on the Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC). The antimicrobial activities of leaf extracts from the two plants highlighted in this study could justify their therapeutic use. These results should be strongly recommended as an alternative to a chemical compound that still represents the problem of toxic residues.
