| 摘 要： | 本文建立了不同加香食品中以1,4-二溴苯和乙酸苯乙酯为内标测定天然有害物侧柏酮、龙蒿脑、黄樟素和甲基丁香酚含量的气相色谱方法,保留时间定性,内标法定量。前处理方法采用同时蒸馏萃取方法以二氯甲烷作为提取剂将待测物从各食品基质中分离。结果表明,在实验浓度范围内,四种待测物与内标物峰面积比值与浓度比值呈现良好线性关系,相关系数为0.99954~0.99973;方法检出限分别为侧柏酮0.16μg/mL、龙蒿脑0.2μg/mL、黄樟素0.2μg/mL和甲基丁香酚0.4μg/mL;空白加标回收率为82.47%~98.06%,相对标准偏差为1.09%~4.05%,获得了良好的准确性和精密度;考察了不同基质对待测物回收率的影响。通过对市场上5种食品的检测,表明该法可实现对样品进行灵敏、准确的定性定量分析,本方法可靠,能满足实际样品的检测及监控的要求。

| Abstract: | A GC method was developed for the determination of some limited used substances such as thujone,estragole,safrole,and methyl eugenol in various food.The internal standard was1,4-dibromobenzene and phenethyl acetate.The substances were identified by retention times and quantified by internal standard.The compounds were isolated from food matrices by employing simultaneous distillation extraction(SDE)technique and using dichloromethane as extraction solvent.The results showed that good linearity for all four ... |
