Abstract

The application provides a kit for detecting drug residues in meat. The kit contains a hybrid cation exchange solid-phase extraction column, an extract of adamantanamine, quinolones and sulfanilamide medicines, a first leacheate, a second leacheate, an eluate and a reconstitution fluid. The invention also provides a drug residue detection method by the use of the kit. Pretreatment methods of the above three medicines are integrated to design a kit for simultaneous pretreatment of drug residues of adamantanamine, quinolones and sulfanilamide medicines. The kit can be used for pretreating the above three medicines simultaneously. After pretreatment, chromatography or mass spectrometry of a sample can be carried out by a conventional technology.

Description

technical field [0001] The invention relates to a detection of drug residues, in particular to a method for detecting drug residues in meat products and a kit thereof. Background technique [0002] At present, many meat companies have to carry out the residue detection of amantadine, quinolones and sulfonamides. The pretreatment of samples is an important step in residue detection, and it is also the most time-consuming and reagent-consuming step. However, the existing pretreatment for the detection of residues of amantadine, quinolones and sulfonamides in meat products can only be used for the pretreatment of a single drug residue, which is inefficient, takes a long time to process, and consumes a lot of organic reagents. , resulting in high cost for meat enterprises to apply. Contents of the invention [0003] The present invention aims to solve the problem in the prior art that the pretreatment of amantadine, quinolones and sulfonamide drug residues in meat products ca...
