PG - 333-6 AB - OBJECTIVE: To establish a method for the determination of zearalenone and its metabolites in grains by capillary electrophoresis. METHODS: The samples were extracted with liquid-liquid partition and ultrasonic extraction, cleaned up with C18 cartridges, then determined by micellar electrokinetic capillary chromatography (MEKC). RESULTS: The limits of detection for Zearalenone (ZON), alpha-Zearalenol (alpha-ZOL), beta-Zearalenol (beta-ZOL), Aflatoxin B1 (AFT B1) and Ochratoxin A (Och A) were 0.0084, 0.081, 0.14, 0.0016 and 0.031 microgram/ml, respectively. Recoveries of all compounds were in the range of 77.9%-103.1%. Relative standard deviations (RSDs) were 0.63%-1.98%. CONCLUSION: This sensitive and accurate method can be used in the determination of zearalenone and its metabolites in grains.
