| 摘 要： | 建立了分子印迹固相萃取-高效液相色谱法测定果汁中展青霉素的方法。浓缩果汁样品经酶解,乙酸-水溶液稀释,分子印迹固相萃取小柱净化后(澄清果汁样品经乙酸-水溶液稀释后,直接进行SPE净化),以Waters XSELECT HSS T3色谱柱为分离柱,以水和乙腈作为流动相,二极管阵列检测器高效液相色谱进行检测,外标法定量。展青霉素在20~1000μg/L质量浓度范围内线性关系良好,相关系数为0.9994,方法的定量限为10.0μg/kg;添加水平为10.0、20.0μg/kg和40.0μg/kg时,加标回收率为83.0%~91.5%,相对标准偏差为2.8%~7.6%。结果表明:该方法准确、高效、特异性好、重现性高,适用于果汁中展青霉素的测定。
