摘要:

建立水产品中苯丙酸诺龙、诺龙残留量的液相色谱- 串联质谱(HPLC-MS/MS)检测方法。样品用混合溶剂提取,提取液经浓缩溶解后采用液液萃取和C18 柱净化,液相色谱- 串联质谱检测。结果表明:苯丙酸诺龙、诺龙在0.005~0.25μg/mL 范围内线性关系良好,在3 个浓度添加水平下,两者的回收率分别为84.2%~91.3%、76.8%~98.6%,相对标准偏差(RSD)分别为6.8%~13.6%、 3.3%~11.3%,最低检测限为5.0μg/kg。

Abstract:

A method was established for the determination of nandrolone and nandrolone phenylpropionate residues in aquatic products. Samples were extracted with mixed solution after enzymatic hydrolysis, purified with liquid-liquid extraction. Then the impurities were removed by C18 column, and the eluant was concentrated and subjected to liquid chromatography-tamden mass spectrometry analysis. Good linear correlation was obtained between the peak area and the concentration in the range of 0.005 0.25μg/mL. The spike recoveries were 76.8%-98.6% and 84.2%-91.3% for nandrolone and nandrolone phenylpropionate standard. The relative standard deviations were all below 13.6%, and the limits of detection was 5.0μg/kg.

Key words: liquid chromatography-tandem mass spectrometry, nandrolone phenylpropionate, residue, aquatic products
