Abstract:
CAY-1 is a fungicidal saponin from the cayenne pepper (Capsicum frutescens) fruit. The saponins 1081 and 919, closely elute with, and are close structural relatives of, CAY-1. Saponin 1081 is poorly antifungal while 919 has no antifungal properties. Nongerminated and germinating conidia of Aspergilus flavus, A. fumigatus, A. niger, Fusarium oxysporum, F. solani, and F. verticilioides were tested against pure CAY-1 and CAY-1:1081:919 at ratios of 8:1:1, 6:2:2 and 4:3:3 and efficacy was determined after various incubation times. Pure CAY-1 and all saponin mixtures were significantly (p
