Multiclass mycotoxin analysis in Silybum marianum by ultra high performance liquid chromatography–tandem mass spectrometry using a procedure based on QuEChERS and dispersive liquid–liquid microextraction

Posted on 26 February, 2013 by fqm302

Ultra high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) has been proposed for the determination of 15 mycotoxins in milk thistle (Silybum marianum), including aflatoxins, fumonisins, trichothecenes, ochratoxin A, citrinin, sterigmatocystin and zearalenone. The mycotoxins were detected by electrospray ionization in … Continue reading →
