Antifungal activities of ethanolic extract from Jatropha curcas seed cake.
Phorbol ester extraction was carried out from Jatropha curcas seed cake, a by-product from the bio-diesel fuel industry. Four repeated extractions from 5 g J. curcas seed cake using 15 ml of 90% (v/v) ethanol and a shaking speed of 150 rev/min gave the highest yield of phosbol esters. The ethanolic extract of J. curcas seed cake showed antifungal activities against important phytofungal pathogens: Fusarium oxysporum, Pythium aphanidermatum, Lasiodiplodia theobromae, Curvularia lunata, Fusarium semitectum, Colletotrichum capsici and Colletotrichum gloeosporiodes. The extract contained phorbol esters mainly responsible for antifungal activities. The extract could therefore be used as an antifungal agent for agricultural applications.
