식육중의 잔류 항생.항균제의 검정에 관한 연구(III) Macrolide계 항생물질인 Erythromycin과 Tylosin의 Gas Chromatography/Mass Spectrometry 동시분석
A study on the determination of residual Antibiotics and Synthetic Antibacterial Agents in Meat(III) Simultaneous Gas Chromatography/Mass Spectrometry Analysis of Erythromycin and Tylosin
초록
In an attempt to quantitate and qualitate residual antibiotics and antibacterial agents n meat simultaneously, we studied a gas chromatogrphy-mass spectrometry (GC/MS) analysis. For a simultaneous analysis of macrolide antibiotics such as erythromycin and tylosin in meat, the homogenization with MeOH, defatting with n-hexane, extraction with CHCl3, elution with CHCl3 : MeOH=2:1 from Sep-Pak silica cartridge, acid gydrolysis, back extraction with CHCl3, and quantitation by selected ion monitoring(SIM) mode after trimethylsilyl derivatization were performed. The recoveries of erythromycin and tylosin (CV,%) at 10 ppm fortification level were 90.59(4.89) and 45.91(0.20) , and the detection limits of those were 0.02 and 2.0
