Abstract This work aims to research new bio-fungicidal molecules based on the essential oils (EO) of Artemisia herba alba Asso, Mentha pulegium L, Rosmarinus officinalis L and Ocimum basilicum L for the food protection and preservation against fungal attacks, also, to determine the chemical composition and the socio-economic interest of oil. The plant material used in this study is represented by the aerial part of O. basilicum L., A. herba-alba Asso, M. pulegium L and the leaves and flowers of R. officinalis L dried for a week, protected from the light and at room temperature. EO chemical composition analysis by GC/MS revealed 36, 26, 34 and 27 constituents for A. herba alba Asso, R. officinalis L, O. basilicum L and M. pulegium L EO, respectively. The antifungal activity of the oils was tested using the direct contact PDA method by determining mycelial growth rate and the minimum inhibitory concentration (MIC). The results of the antifungal study showed that all the fungal strains tested are sensitive to different concentrations of the EO applied with a great antifungal potential by an MIC between 139.08 and 1082.76 μg/ml. Thanks to the antifungal power of the EO of the plants studied, the latter demonstrate that the can constitute an important source of several active ingredients including the antifungal activity necessary for a bio-fungicidal product with a more advantageous national socioeconomic level.
