Embodiment

[0049] 1. Preparation of standard solution

[0050] Preparation of standard solution: Accurately weigh an appropriate amount of standard products of ofloxacin and ofloxacin-D3, and dissolve them in methanol to prepare a 100.0-1000.0 mg / L standard solution.

[0051] Preparation of standard stock solution: Pipette an appropriate amount of standard solution into a 10.0mL volumetric flask, dilute to the mark with methanol, and prepare a 1.0mg / L standard stock solution.

[0052] Preparation of standard working solution: properly dilute the standard stock solution with methanol-water solution (1:1).

[0053] 2. Linear regression equation and detection limit

[0054]Prepare a series of ofloxacin standard working solutions with a concentration of 0.05 μg / L-100.0 μg / L. The internal standard ofloxacin-D3 concentration is 50.0 μg / L, and the peak area ratio (y) is used for the content (x). Figure, the result shows that, in the scope of 0.05 μ g / L-100.0 μ g / L, peak area ratio (y) and con...

Abstract

The invention belongs to the technical field of detection of drug residues, and in particular relates to a detection method of ofloxacin residues in livestock and poultry hair. This method takes livestock and poultry hair as the detection object, without slaughtering chickens, pigs, cattle and other livestock and poultry, and realizes the detection of live livestock and poultry; Contaminated, difficult to store, inconvenient sampling and other issues; due to the long hair growth cycle, it is more accurate to monitor whether ofloxacin is used in the growth process of livestock and poultry, so as to achieve the purpose of supervision of food safety production of livestock and poultry, and the detection method operation Simple, accurate results, no false positives, false negatives, etc., and high sensitivity.

Description

technical field [0001] The invention belongs to the technical field of detection of drug residues, and in particular relates to a detection method of ofloxacin residues in livestock and poultry hair. Background technique [0002] Ofloxacin is a third-generation quinolone antibacterial drug with good antibacterial effect. According to the safety evaluation of veterinary drugs organized by the Ministry of Agriculture, various salts, esters and various preparations of ofloxacin APIs may cause harm to the breeding industry and human health or have potential risks. Long-term consumption of ofloxacin drug residues in meat food can cause human respiratory tract infection, gene mutation, and carcinogenicity. According to Article 69 of the "Regulations on the Administration of Veterinary Drugs", the Ministry of Agriculture Announcement No. 2292 decided to stop the use of ofloxacin and other 4 kinds of veterinary drugs in food animals, and revoke the approval number of relevant veter...
