Abstract

The invention relates to an antibiotic detection method. The method concretely comprises the following steps: (1) carrying out pretreatment for vegetable samples in order to obtain an antibiotic extract; (2) carrying out extraction for the antibiotic extract in order to obtain an antibiotic eluate; (3) evaporating the antibiotic eluate to dryness by a rotary evaporator, carrying out volumetric flask preparation with an initial mobile phase, and carrying out filtering with a syringe filter in order to obtain an antibiotic liquid to be measured; (4) carrying out detection for the antibiotic liquid to be measured by optimized high performance liquid chromatography-tandem mass spectrometry in order to detect antibiotics to be measured. The method for detecting 11 kinds of antibiotic residues in vegetable samples has the advantages of high recovery rate and low detection limit, and overcomes the disadvantages and insufficient that antibiotic detection methods in the prior art have high cost, few antibiotic detection kinds, and high detection limit; a base for assessing antibiotic environmental behaviors and risks is established.

Description

technical field

[0001] The invention relates to an antibiotic detection method, in particular to a method for simultaneously detecting multiple antibiotic residues in vegetables by using high-performance liquid chromatography tandem mass spectrometry. Background technique

[0002] Antibiotics refer to substances with the same or similar structure that are obtained from bacteria, actinomycetes, fungi and other microorganisms through cultivation or synthesized by chemical synthesis, and have the ability to kill or inhibit pathogenic microorganisms. In recent years, a large number of antibiotics have been widely used in livestock and poultry breeding as veterinary drugs and feed additives, and play an important role in the prevention and control of animal diseases, improving feed conversion efficiency, and promoting animal growth and development. However, antibiotics that enter animals through oral or intramuscular injection cannot be fully absorbed and utilized. The amount exc...
