The lowest Minimum Inhibitory Concentration (MIC) values against G. candidum and P. digitatum were obtained in the extract of Marrubiumperegrinum L. (250 and 125 mu g/ml). In 1000 mu g/ml, the extracts of Melissa officinalis showed 100% inhibition on the spore germination of G. candidum and P. digitatum. In the Scanning Electron Microscope (SEM) observations of G. candidum and P. digitatum that was subjected to M peregrinum extract (4MIC) degenerative changes in the hyphal morphology were seen in the form of cell wall degradation, lysis and collapsing. The highest values of total phenolics were obtained from Mentha pulegium extracts (739.57 mg GAE/g). The lowest EC50 values (0.08 mg/ml) were found in the extracts of M peregrinum and Sideritis montana. The highest flavanol content was determined from M. officialis exctracts (12.71 mg CE/mg). This study demonstrates M. peregrinum extracts may possess high antifungal activity against G. candidum and P. digitatum.en10.25083/rbl/24.5/798.806info:eu-repo/semantics/openAccessGeotrichum CandidumPenicillium DigitatumAntifungal ActivityPlant ExtractSEMTotal Phenolic ContentEssential OilsIn-VitroMoroccan PlantsCausal AgentExtractsVivoPartsArticle245798806Q4WOS:000492689700007
