摘　　要：本文对液相色谱–串联质谱法测定食用植物油中乙基麦芽酚的方法进行了条件优化。结果表明,在10~200 ng·mL^(-1)线性良好,相关系数R^(2)=0.9972,检出限为0.3μg·kg^(-1),定量限为1μg·kg^(-1),平均回收率为92.4%~98.6%,相对标准偏差为2.4%~3.8%。该方法适用于食用植物油样品中乙基麦芽酚的日常检测。The conditions for the determination of ethyl maltol in edible vegetable oil by liquid chromatography-tandem mass spectrometry were optimized.The results showed that the linearity was good at 10~200 ng·mL^(-1),the correlation coefficient R^(2)=0.9972,the detection limit was 0.3μg·kg^(-1),the limit of quantitation was 1μg·kg^(-1),the average recovery was 92.4%~98.6%,and the relative standard deviation was 2.4%~3.8%.This method is suitable for the daily detection of ethyl maltol in edible vegetable oil samples.
