Abstract:
Citrus macroptera, commonly known as 'Wild Lime,' is an underexplored fruit with promising medicinal properties. This study aimed to assess the antifungal and antioxidant activities of Citrus macroptera essential oil against three prevalent Plant fungal pathogens, namely Macrophomina phaseolina, Fusarium oxysporum f. sp. cubense and Colletotrichum gloeosporioides. In vitro assay results indicated that Colletotrichum gloeosporioides (98.88%) showed the highest percentage of inhibition, followed by Macrophomina phaseolina (92.96%) and Fusarium oxysporum (77.40%). The essential oil of Citrus macroptera exhibited good antioxidant potential with an IC₅₀ value of 195.96 µg/ml, which revealed its extent of application in both the pharmaceutical and agricultural sectors. Future research is likely to integrate and contrast the identification of the chemical composition of the essential oil, as well as the study of the active component responsible for its antifungal and antioxidant effects.
