Trichothecenes are a group of naturally occurring sesquiterpene poly alcohols and esters with a common skeleton of 12,13-epoxytríchothec-9-ene. The interest in these compounds started by the isolation of a trichothecin compound from a culture of Trichothecium roseum (Freeman and Morrison, 1948 and 1949a). To date, over 80 naturally occurring trichothecenes have been reported (McDougal and Schmuff, 1985). Trichothecenes are classified into three main categories; simple, macrocyclic, and trichoverroid trichothecenes (Jarvis et al., 1982). These compounds have been found to be associated with cultures of the fungi imperfecti genera Fusarium, Trichoderma, Myrothecium, Trichothecium, Cephalosporium, Stachybotrys, Verticimonosporium and Cylindrocarpon (Ueno, 1983).
