实时直接分析-串联质谱法测定葡萄酒中赭曲霉毒素A
Determination of ochratoxin A in wine by direct analysis in real time-tandem mass spectrometry
摘要
Abstract
A method for the determination of ochratoxin A (OTA) in wine was developed using direct analysis in real time-electrospray ionization tandem mass spectrometry (DART-MS/MS).The sample was extracted with ethyl acetate and purified by votexing with ODS powder,detected using DART-MS/MS.The results showed that the average recoveries ranged from 88.7％ to 105.7％ with the RSDs of 8.5％-12.8％ at three spiked levels of 1.0,2.0,and 10 μg/kg.The LOQ was 0.5 μg/kg.The proposed method was accurate,rapid and reliable,which can be successfully applied to the qualitative and quantitative analysis of ochratoxin A in wine.关键词
