Multiresidue mycotoxin analysis of conventional and organic agriculture commodities by UPLC-MS/MS

Popis výsledku v původním jazyce

EAlkaloids are widely distributed plant metabolites, which are grouped by typical structural characteristics into large families such as pyrrolizidine alkaloids (PAs), which include more than 350 individual heterocyclic compounds. Intoxications caused byPAs are described by hepatotoxicity with tendency to cause hemorrhagic necrosis and veno-occlusion in liver, pneumotoxicity, carcinogenity, mutagenity and genotoxicity. Thus there is a need for methods that allow determination of these dangerous plant toxins. In this study fast, reliable and sensitive approach is proposed allowing simultaneous screening, identification, and quantification of PAs in feed samples. PAs including monocrotaline, senkirkine, senecionine, seneciphylline and retrorsine were determined by ultra performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS). Sample preparation is based on modified QuEChERS approach. Mean recovery, precision, matrix effects and limits of quantification (LOQ) w
