A Study on the Simultaneous Determination of Residual Zeranol, Zearalenone and Their Metabolites in Beef by Gas Chromatography/Mass Spectrometry
Gas Chromatography/Mass Spectrometry에 의한 우육 중의 잔류 Zeranol, Zearalenone 및 그 대사산물들의 동시 분석법에 대한 연구
Abstract
A Simultaneous determination method was improved for the determination and confirmation of zeranol, zearalenone, as well as their isomers and metabolites, in beef. The analytes were extracted from tissue by CH3CN, hydrolyzed enzymatically(for glucuronide conjugates), cleaned up by a strong basic anion exchange resin combined with a liquid/liquid partitioning, derivatized using MSTFA and confirmed, quantified by GC/MS/SIM with a internal standard, zearalane. The results were as follows : (1) all the estrogens were separated on the GC/MS chromatogram under the extraction method and the chromatographic conditions improved, the retention times of zearalane-TMS2, zearalanone-TMS2, zearalenone-TMS2, zeranol-TMS3, taleranol-TMS3, and
