Abstract
Fungi of the genera Colletotrichum and Fusarium affect agricultural foodstuffs in crop yield and economic loss and the excessive use of antifungal treatments has resulted in antifungal drug resistance. Plants are rich sources of a wide variety of bioactive secondary metabolites reported to have in vitro antifungal properties. Therefore, this study was designed to perform phytochemical screening, high-performance thin layer chromatography (HPTLC) fingerprint profile, and in vitro antifungal activity of Jatropha platyphylla bark and leaf methanolic extracts against Colletotrichum cliviae, Fusarium oxysporum f. spp. lycopersici and F. oxysporum f. spp. radicis-lycopersici. The HPTLC chromatogram analysis confirmed the presence of terpenoids and flavonoids. Additionally, apigenin 7-O-glucoside was identified in bark and leaf samples and confirmed by the chromatogram standards by comparing its retention factor (Rf = 0.977). The methanolic bark and leaf extract added at a concentration of 0.05% stopped C. cliviae mycelium growth significantly by 96.50% and to a lesser degree to both Fusarium species. In light of the in vitro test results obtained, the methanolic extracts of J. platyphylla appeared to be an excellent source of antifungal components whose potential would allow the development of this species into treatments for the biological control of fungal diseases.
