Preparation and Determination of Antibiotics Residues in Fresh Meat Using Auto Solid Phase Extraction and HPLC
-
摘要: 对采用固相萃取技术萃取的鸡肉和猪肉样品进行净化处理，然后采用高效液相色谱对其中的四环素类抗生素进行同时检测。试验得到土霉素、四环素和金霉素3种四环素类抗生素在鸡肉中的加标回收率分别为87.4%～97.9%、89.2%～92.7%和89.7%～99.4%，猪肉中的加标回收率分别为83.9%～97.9%、90.6%～108.0%和98.1%～109.3%。Abstract: A solid phase extraction method was established for preparation of antibiotics residues from chicken and pork.They were detected simultaneously using high performance liquid chromatography.The spiked recovery rate of terramycin，tetracycline，aureomycin ranged from 87.4%～97.9%，89.2%～92.7% and 89.7%～99.4% in chicken.The spiked recoveries ranged from 83.9%～97.9%，90.6%～108.0% and 98.1%～109.3% in pork.
