Aminoglycosides are a widely used group of antibiotics in veterinary medicine. However, misuse and abuse of these drugs can lead to residues in the edible tissues of animals. Due to the toxicity of aminoglycosides and the exposure of consumers to the emergence of drug resistance, new methods are being sought to determine aminoglycosides in food. The method presented in this manuscript describes the determination of twelve aminoglycosides (streptomycin, dihydrostreptomycin, spectinomycin, neomycin, gentamicin, hygromycin, paromomycin, kanamycin, tobramycin, amikacin, apramycin, and sisomycin) in thirteen matrices (muscle, kidney, liver, fat, sausages, shrimps, fish honey, milk, eggs, whey powder, sour cream, and curd). Aminoglycosides were isolated from samples with extraction buffer (10 mM NHOOCH, 0.4 mM NaEDTA, 1% NaCl, 2% TCA). For the clean-up purpose, HLB cartridges were used. Analysis was performed using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) with a Poroshell analytical column and a mobile phase of acetonitrile and heptafluorobutyric acid. The method was validated according to Commission Regulation (EU) 2021/808 requirements. Good performance characteristics were obtained for recovery, linearity, precision, specificity, and decision limits (CCα). This simple and high-sensitivity method can determine multi-aminoglycosides in various food samples for confirmatory analysis.
氨基糖苷类抗生素在兽医临床上被广泛应用。然而,这些药物的滥用和误用可能导致动物可食用组织中残留。由于氨基糖苷类抗生素的毒性以及消费者接触到耐药性的出现,人们正在寻找新的方法来检测食品中的氨基糖苷类抗生素。本文介绍的方法描述了在 13 种基质(肌肉、肾脏、肝脏、脂肪、香肠、虾、鱼蜜饯、牛奶、鸡蛋、乳清粉、酸奶油、凝乳)中测定 12 种氨基糖苷类抗生素(链霉素、双氢链霉素、壮观霉素、新霉素、庆大霉素、潮霉素、巴龙霉素、卡那霉素、妥布霉素、阿米卡星、安普霉素和西索霉素)的方法。氨基糖苷类抗生素用提取缓冲液(10mM NHOOCH、0.4mM NaEDTA、1%NaCl、2%TCA)从样品中分离出来。为了净化目的,使用了 HLB 小柱。分析采用超高效液相色谱-串联质谱法(UHPLC-MS/MS),使用 Poroshell 分析柱和乙腈和七氟丁酸作为流动相。该方法按照欧盟委员会 2021/808 号法规的要求进行了验证。该方法在回收率、线性、精密度、特异性和决策限(CCα)方面均表现出良好的性能特征。这种简单且高灵敏度的方法可以用于各种食品样品中的多氨基糖苷类抗生素的确证分析。
