Honey is a natural food widely consumed due to its high content in nutrients and bioactive substances. In order to prevent hive infections, xenobiotics such as pesticides and antibiotics are commonly used. Chloramphenicol (CAP) is a broad-spectrum antibiotic used to treat honeybee larvae diseases. However, CAP has toxic and nondose-dependent effects in sensitive subjects; for this reason, its use has been prohibited in food-producing animals, such as the honeybee. In this study, we proposed a rapid, simple, and cheap analytical method, based on salting-out assisted liquid-liquid extraction coupled with UHPLC MS/MS detection for the accurate determination of CAP in honey to be used in routine analyses. The parameters that influence the extraction efficiency have been optimized using an experimental design in order to maximize the recovery of the analyte by reducing the matrix effects. Therefore, the developed method was internally validated according to the 2002/657/EC Decision guidelines and applied to the analysis of 96 honey samples.
蜂蜜是一种深受人们喜爱的天然食品,因其富含营养物质和生物活性物质。为了预防蜂房感染,通常会使用农药和抗生素等外来化合物。氯霉素(CAP)是一种广谱抗生素,用于治疗蜜蜂幼虫疾病。然而,CAP 对敏感人群具有毒性和非剂量依赖性效应;因此,其在产食动物(如蜜蜂)中的使用已被禁止。在这项研究中,我们提出了一种快速、简单且廉价的分析方法,基于盐析辅助液液萃取结合 UHPLC-MS/MS 检测,用于常规分析中蜂蜜中 CAP 的准确测定。通过实验设计优化了影响萃取效率的参数,以通过减少基质效应来最大限度地提高分析物的回收率。因此,该方法根据 2002/657/EC 号决定准则进行了内部验证,并应用于 96 个蜂蜜样品的分析。
