[Simultaneous determination of 15 water-holding functional drugs in animal tissues using ultra performance liquid chromatography-tandem mass spectrometry].

≥ 0.9949), and the limits of quantification were all less than 1.0 μg/kg in animal tissues.The recoveries of the 15 water-holding functional drugs ranged from 60.0%-111.0% in animal tissue samples, with the intra and inter RSDs of 0.56%-11.5% and 2.31%-14.8%, respectively.The method can meet the requirements for the determination of the drug residues in animal tissues.It provides a new idea to identify potential hazards in animal-derived foods and to monitor illegal addition.
