[f. mod.L. Trichothec-ium, name of a genus of fungi (H. F. Link 1809, in Mag. d. Ges. Naturforschender Freunde zu Berlin III. 18), f. tricho-1 + thecium: see -in1.]
A crystalline trichothecene, C15H19O3·O·CO·C3H5, that is an ester of butenoic acid produced by the fungus Trichothecium roseum and is toxic to some other fungi.
1948Freeman & Morrison in Nature 3 July 30/1 Antagonistic activity to other fungi by Trichothecium roseum Link..has been reported... The name ‘trichothecin’ is suggested for the active substance. 1981Cole & Cox Handbk. Toxic Fungal Metabolites v. 152 Examples of trichothecenes that do not contain a carbonyl function at C-8 are T-2 toxin,..and trichothecin.
Hence trichoˈthecene, any of a class of sesquiterpenoids based on a tetracyclic ring system C15H22O2.
1971Analytical Biochem. XLIII. 327 The trichothecenes are a family of closely related tetracyclic sesquiterpenoid metabolites of various strains of Fusarium, Trichoderma, Trichothecium, Myrothecium, and other species of imperfect fungi commonly found in soil, and on grains and other foods and feeds. 1978Experientia XXXIV. 1333/1 Samples from 2 lots of corn in France suspected of causing infertility, hyperestrogenic signs and feed refusal in swine were analyzed for zearalenone and trichothecenes. 1982Daily Tel. 24 Mar. 18 Trichothecene toxins should be seen as the murderous successors to mustard gas. |
