| 摘 要： | 建立高效液相色谱法测定芝麻油中叔丁基羟基茴香醚(BHA)、2,6-二叔丁基对甲酚(BHT)、特丁基对苯二酚(TBHQ)的含量。用25mL甲醇分5次涡旋超声提取芝麻油中的BHA,BHT,TBHQ,以La ChromC18(250mm×4.6mm,5μm)为色谱柱,以甲醇-0.5%甲酸水溶液为流动相进行梯度洗脱,流量为1.0mL/min,进样体积为5μL,柱温为35℃,检测波长为280nm。BHA,BHT,TBHQ的质量浓度在20~300mg/L范围内与其色谱峰面积呈良好的线性关系,相关系数大于0.999,方法检出限为0.5~1.0mg/kg。样品加标回收率为95.1%~99.8%,测定结果的相对标准偏差为2.1%~4.7%(n=6)。该方法操作简单,试剂用量少,准确度高,精密度好,适用于芝麻油中BHA,BHT,TBHQ含量的日常检测。
