摘要: 目的 建立高效液相色谱法(HPLC)同时测定毒饵中杀鼠灵、溴敌隆、大隆3种抗凝血灭鼠剂的含量。方法 在C18色谱柱,以甲醇+0.1%乙酸(90+10)为流动相,检测波长为265 nm,柱温为室温下进行检测。结果 3种灭鼠剂在5.0~300.0μg/ml浓度之间呈现良好的线性关系,杀鼠灵:Y=2.58×107x-1.23×105,r=0.9996;溴敌隆:Y=2.09×107x+1.56×105,r=0.9995;大隆:Y=1.79×107x+1.02×105,r=0.9992;相对标准偏差为1.03%~2.16%,回收率在93.7%~98.8%之间。结论 HPLC法操作简便、准确、快速,可同时对这3种抗凝血灭鼠剂含量进行检测。

Abstract: Objective To establish a high performance liquid chromatography method for determination of the concentration of warfarin,bromadiolone,brodifacoum in the poison bait.Methods Warfarin,bromadiolone and brodifacoum were separated on a C18 column using methanol(50%): 0.1% aceticacid(50%) as the mobile phase at a flow rate of 1.0 ml/min,and detection wave 265 nm.Results The linear range were 5.0 μg/ml to 300.0 μg/ml,warfarin Y=2.58×107x-1.23×105,r=0.9996;bromadiolone Y=2.09×107x+1.56×105,r=0.9995;brodifacoum Y=1.79×107x+1.02×105,r=0.9992;the relative standard deviation were 1.03% to 2.16% and the rate of recovery were 93.7% to 98.8%.Conclusion The method established in the present paper is simple,precise,fast and suitable for determination the concentration of warfarin,bromadiolone,brodifacoum in poison bait.
