“…Furthermore, Seitz et al (1975b) reported that the presence of AME (Figure IB) could, under certain circumstances, interfere with zearalenone determinations. A range of analytical techniques including thin-layer chromatography, highperformance liquid chromatography, gas chromatography, and mass spectrometry have been employed for the determination of zearalenone and its derivatives (Moller and Josefsson, 1978; Ware and Thorpe, 1978;Scott et al, 1978;Diebold et al, 1979; Smyth and Frischkorn, 1980;Cohen and Lapointe, 1980;Gimeno, 1983;Swanson et al, 1984;Trenholm et al, 1984; Chang and De Vries, 1984; Bennett et al, 1985; Bagneris et al, 1986) as well as for the determination of the Alternaría toxins AOH and AME (Pero et al, 1971; Seitz et al, 1975a; Seitz and Mohr, 1976;Stinson et al, 1980;Heisler et al, 1980;Chu and Bennett, 1981;Wittkowski et al, 1983;Stack et al, 1985).…”
