Study of the natural occurrence of T-2 and HT-2 toxins and their glucosyl derivatives from field barley to malt by high-resolution Orbitrap mass spectrometry.

摘要: This paper reports a new method for the determination of T-2 and HT-2 toxins their glucosylated derivatives in cereals, some survey data aimed at obtaining more comprehensive information on co-occurrence naturally contaminated cereal samples. For these purposes, barley samples originating from Northern Italian area were analysed by LC-HRMS presence T-2, relevant glucosyl derivatives. Quantitative analysis glucosides was performed first time using recently made available standard glucoside. The derivative detected levels up to 163 µg kg–1 17 18 unprocessed grains, whereas monoglucosyl toxin only few low µg kg–1 levels. ratio between (sum glucosides) native HT-2) ranged 2% 283%. Moreover, taking advantage...
