[方法]以乙腈为提取溶剂,用Florisil固相萃取柱净化,采用GC-ECD测定,检测蜂王浆中氟胺氰菊酯的残留量。[结果]氟胺氰菊酯的回收率及精密度较高,标准工作曲线的线性相关系数为0.9995,氟胺氰菊酯的加标回收率为82.68%~94.70%,相对标准偏差为3.49%~5.52%,方法最小检出限为0.008 mg/kg。[结论]该方法操作简单,乙腈提取时,则避免乳化现象,样品提取、净化效率高,而且简便、重现性好,适合大批量样品的检测。
[Method] Acetonitrile was used as the extraction solvent, purified with Florisil solid phase extraction column, and the residual amount of fluvalinate in royal jelly was determined by GC-ECD. [Result] The fluvalinate had higher recovery and precision, the linear correlation coefficient of standard working curve was 0.9995, the spiked recoveries of fluvalinate were 82.68% ~ 94.70%, and the relative standard deviations were 3.49% ~ 5.52%, the minimum detectable limit was 0.008 mg / kg. [Conclusion] The method was simple in operation, avoiding the emulsification when extracted with acetonitrile. The extraction and purification of samples were efficient, simple, reproducible and suitable for the detection of large quantities of samples.
