摘    要:目的]建立蜂胶中氟胺氰菊酯和氟氯苯氰菊酯残留的测定方法。方法]以石油醚为溶剂提取样品,采用凝胶渗透色谱法净化样品,采用气相色谱法测定氟胺氰菊酯和氟氯苯氰菊酯残留。结果]匀浆提取的提取效果远远好于震荡提取的提取效果。石油醚的提取效果比石油醚-丙酮混合液的提取效果好。与丙酮-石油醚(9:1)和石油醚-乙酸乙酯(95:5)相比,石油醚-乙酸乙酯(98:2)的净化效果最理想。氟胺氰菊酯和氟氯苯氰菊酯的回收率均在69.0%~96.4%,相对标准偏差均在1.27%~7.69%,表明该方法的准确度和精密度均能达到残留分析的要求。氟胺氰菊酯和氟氯苯氰菊酯的检测限均为0.05mg/kg。结论]该方法可以有效监控蜂胶中相应药物的残留,提高国产蜂胶的品质和国际竞争力。

关 键 词:蜂胶  氟胺氰菊酯  氟氯苯氰菊酯  凝胶渗透色谱  气相色谱
