Abstract

Fungal diseases, both pre- and post-harvest, are currently difficult to control-increased antifungal resistances have further stimulated the search for natural alternatives. The objective of the present research work was to evaluate the antifungal activities of Mentha pulegium essential oil (EO) and its major constituents. The EO was obtained from hydro distillation of fresh leaves, and composition was determined using gas chromatography/mass spectrometry (GC/MS). The main components were identified as pulegone (29.33%), menthol (28.79%), menthone (20.48%), and isopulegol (9.75%). EO and isopulegol exhibited the highest antifungal activity, with half maximal effective concentrations (EC50) inhibiting mycelial activity of Monilinia fructicola at 24.6 mu g/mL and 20.8 mu g/mL, respectively, and against Botrytis cinerea, at 301.45 mu g/mL and 333.84 mu g/mL, respectively. These findings could lay the foundation for developing antifungal agents of agricultural value.
