Abstract

The invention relates to a method for determining residual medicaments in mutton, and in particular relates to a method for determining multiple sedative type medicaments in mutton at the same time. The residual sedative type veterinary medicaments refer to zolpidem, haloperidol, chlordiazepoxide, promethazine, nitrazepam, chlorpromazine hydrochloride, perphenazine, fluphenazine hydrochloride, clonazepam, xylazine hydrochloride, propionylpromazine, carazolol, acepromazine, droperidol and azaperone. The method has the advantage that the residual amounts of 15 types of sedative type medicaments in mutton are determined through high-resolution liquid chromatography-tandem mass spectrometry. The method is high in sensitivity and high in recovery rate, and can meet the detection requirements on veterinary medicaments.

Description

technical field [0001] The invention relates to a method for detecting residual drugs in meat, in particular to a method for simultaneously measuring multiple sedative drugs in meat. Background technique [0002] Sedatives refer to a class of drugs that can slightly inhibit the central nervous system and weaken functional activities, thereby eliminating restlessness and restoring tranquility. In recent years, driven by economic interests, individual livestock breeders have added such drugs in the process of raising livestock and poultry without authorization to play the role of sedation and hypnosis, weight gain and fattening, and shortening the time for slaughter; in addition, in the process of animal transportation, for To reduce animal death and weight loss, to prevent the reduction of meat quality, these drugs are also often used to reduce the loss caused by stress. Illegal use of such drugs will inevitably leave their original form and metabolites in food of animal ori...
