“…Derivatives were produced by using trimethylsilyl N,Ndimethylcarbamate (Fluka) according to the method of Kientz & Verweij (1986) and analysed by gas chromatography (GC-FID, CP 9000, Chrompack) on a CP SIL 5CB capillary column (Chrompack). Mycotoxins were identified and quantified by means of the following standards : 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol, 3-acety1-diacetoxyscirpeno1, acetyl T-2 toxin, deoxynivalenol, 4,15-diacetoxyscirpenol, fusarenon-X, HT-2 toxin, iso-T-2 toxin, 15-monoacetoxyscirpenol, neosolaniol, scirpentriol, T-2 tetraol, T-2 toxin, T-2 triol (Sigma) and nivalenol (Serva).…”

“…Estão disponíveis diversos sistemas para derivação como anidrido trifluoro acético (TFAA), heptafluorobutirilimidazol (HFBI), pentafluorobutirilimidazol PFBI), trimitilsilil (TMS), bistrimetilsililacetamida (BSA), hexametildisilazano (HMDS) e trimetilsililimidazol (TMSIM) [7,9,31]. O emprego destes reagentes de derivação reduz a polaridade dos grupamentos livres, aumenta a pressão de vapor dos compostos, possibilitando a separação de substâncias muito semelhantes entre si no estado natural e introduz grupos que tornam o composto adequado ao sistema de detecção empregado [1,11].…”

“…Tal observação, também foi relatada por GILBERT et al [7], SCOTT [22], KIENTZ & VERWEIJ [9]. Não foram observadas diferenças significativas nas áreas relativas obtidas quando foram avaliados o tempo e temperatura de derivação para o catalisador piridina.…”

“…Typical analysis of T2 toxin involves solvent extraction and cleanup with a solid phase extraction column followed by detection using either thin layer chromatography [4] or capillary gas chromatography [5]. Immunological methods have also been developed for the detection of T2 toxin.…”
