개요

8,9-dihidro derivate of aflatoxin B1. Apotent hepatotoxic and hepatocarcinogenic mycotoxin

application：

Aflatoxin B2 may be used as a reference standard for the determination of aflatoxin B2 in animal feed by high performance liquid chromatography with fluorescence detection (HPLC-FLD), as well as quick, easy, cheap, effective, rugged and safe (QuEchERS) extraction method combined with ultra-high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS), in eggs by QuEchERS extraction method followed by analysis using UHPLC with tandem mass spectrometry (MS/MS) operating on electrospray-ionization interface (ESI) mode, in Brazil nuts by immunoaffinity column (IAC) and clean-up HPLC-FLD and in plant-based milk and dairy products by dispersive liquid-liquid microextraction (DLLME), QuEchERS extraction method and HPLC-FLD.
