HPLC法测定水产品中阿苯达唑及其主要代谢物残留的研究

论文编号:SW080论文字数:10084,页数:28

摘 要:本文主要阐述了应用高效液相色谱(HPLC)方法测定水产品中阿苯达唑(ABZ)及其两种主要代谢物砜(ABZSO2)、亚砜(ABZSO)残留量的研究。色谱条件是:色谱柱为ZORBAX-SB 5μm C18柱;流动相是酸化乙腈:水(25:75;v/v);甲醇-磷酸缓冲液(75︰25;v/v),流速是1.0mL/min,柱温是30℃,选择的检测波长是295.4nm。采用甲醇:磷酸缓冲液=75:25定容系列标准液,阿苯达唑、阿苯达唑砜、阿苯达唑亚砜在0.1~10μg/mL范围内线性关系良好,加标浓度在100μg/kg~500μg/kg时,回收率分别ABZSO为83%~95%;ABZSO2为85%~97%;ABZ为70%~80%。研究结果显示,该方法的最低检测限、准确度和精密度均符合残留检测方法的要求。此检测分析方法处理样品快速、高效、准确,可作为水产品中阿苯达唑及其主要代谢物的有效检测方法。

Determination of Albendazole and its metabolites in Aquatic products by HPLC

Abstract: The determination of Albendazole and its metabolites in aquatic products was established by using high performance liquid chromatography (Agilent-1100, USA) with a photodiode array detector detector (DAD, USA), a C18 column (ZORBAX-SB). The mobile phase was a mixture of acidified acetonitrile and water (25/75, v/v) and a mixture of methanol and phosphate buffer (75/25, v/v). 20 µl samples at room temperature injected onto the column through a 20 µl sample loop. Column temperature is 300C.The mobile phase rate was delivered at 1.0 ml/min. Detection wavelength: 295.4nm. In the range of 0. 1 - 10μg/ml, the results of Albendazole and its metabolite are linearly dependent. The mean extraction recoveries of Albendazole and its metabolites ranged from 80% to 90%. The method of determining the Albendazole and its metabolites in aquatic product was established by using reversed-phase HPLC, which had characters of simple and rapid operation, high yield and good reproducibility.

Keywords:Aquatic products, high performance liquid chromatography, Albendazole and its metabolites
