摘要:

试验旨在建立一种同时检测鸡蛋中5种青霉素类药物残留的高效液相色谱紫外检测法。鸡蛋经乙腈提取、正己烷脱脂、旋转蒸发浓缩和衍生化后,采用高效液相色谱法分离检测。结果显示,氨苄西林(ampicillin,AMP)、氯唑西林(cloxacillin,CLO)、苯唑西林(oxacillin,OXA)、阿莫西林(amoxicillin,AMO)及普鲁卡因青霉素(penicillins G procaine,PRO)在10~1 000 μg/kg呈良好线性关系,R2>0.999;检测限为1.5 μg/kg(S/N=3),定量限为5.0 μg/kg(S/N=10),添加平均回收率为62.04%~93.13%,相对标准偏差为3.91%~13.69%,批内相对标准偏差为3.98%~14.71%,批间相对标准偏差为4.26%~12.71%。表明本试验建立的高效液相色谱紫外法重复性和灵敏度较高,适用于鸡蛋中的5种青霉素类药物残留检测。

Abstract:

This study was aimed to develop a method for simultaneous determination of five kinds of penicillins in eggs by high performance liquid chromatography-ultraviolet detection (HPLC-UVD). The eggs samples were extracted by acetonitrile,degreased by n-hexane,concentrated by rotary evaporation,derivatization,and then was separated by HPLC. The results showed that the calibration curves of five kinds of penicillins were linear correlated in the concentration ranges of 10 to 1 000 μg/kg with the correlation coefficients >0.999,which the limits of detection and quantification were 1.5 μg/kg (S/N=3) and 5.0 μg/kg (S/N=10),respectively. The average recoveries were 62.04% to 93.13%,the relative standard deviations were 3.91% to 13.69%.And the intra-day and inter-day RSDs were 3.98% to 14.71% and 4.26% to 12.71%,respectively. The developed method was suitable for detecting five kinds of penicillins residues in eggs with high repeatability and sensitivity.
