摘  要:
建立超高效液相色谱-串联质谱技术同时检测畜肉中3种儿茶酚胺类物质。畜肉样品用高氯酸溶液提取,经混合阳离子固相萃取小柱净化,HILIC Plus色谱柱(4.6 mm×100 mm,3.5μm)分离,流动相分别为甲酸-水(1∶99,V/V)和乙腈,采用电喷雾离子源,正离子多反应监测,对儿茶酚胺类药物进行检测,外标法实现定量分析。结果表明:3种儿茶酚胺类药物在40~1 000 ng/mL范围内线性良好,相关系数大于0.99,畜肉中检出限(R_(SN)≥3)为10μg/kg,定量限(R_(SN)≥10)为40μg/kg;添加量为40~1 000μg/kg的3种儿茶酚胺类物质的回收率均在75.48%~91.25%之间,方法的精密度在1.2%~4.6%之间(n=6)。该方法前处理简单、快速、准确,为畜肉中儿茶酚胺的检测提供方法。

摘  要:
This study aimed to establish a method for simultaneous qualitative and quantitative analysis of three catecholamines(CAs) in livestock meat by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLCMS/MS). The samples were homogenized, extracted with perchloric acid solution, and purified on a PCX solid phase extraction cartridge. The chromatographic separation was achieved on an HILIC Plus column(4.6 mm × 100 mm, 3.5 μm) using a mobile phase consisting of acetonitrile and formic acid in water(1:99, V/V). The analytes were ionized by positive electrospray(ESI+), detected in the multiple reaction monitoring mode(MRM) and quantified by the external standard method. The results indicated that a good linearity over the concentration range of 40–1 000 ng/mL was observed for all the analytes with correlation coefficients greater than 0.99. The limits of detection(LOD) and quantification(LOQ) were 10 and 40 μg/kg, respectively. The average recoveries of the CAs ranged from 75.48% to 91.25% with relative standard deviations(RSDs) of 1.2%–4.6%(n = 6). The method is sensitive, simple, rapid and accurate and can meet the requirements for practical analysis.
