摘  要:
为了建立超高效液相色谱-串联质谱法测定饲料中18种喹诺酮类药物的分析方法,以0.1%乙酸乙腈提取饲料样品中的待测物,HLB柱净化,超高效液相色谱-串联质谱法测定,氘代同位素内标法定量。18种喹诺酮类药物在线性范围为0~1.0 mg/L,线性关系良好,相关系数分别在0.9989~0.9999之间,方法的检测限为0.005~0.2 mg/kg。在不同饲料中添加浓度范围为0.1~5.0 mg/kg,平均回收率为43.0%~101%,相对标准偏差小于11.2%。结果表明,该方法灵敏、高效、抗干扰力强,适用于饲料中的18种喹诺酮类药物的测定。

摘  要:
An ultra high performance liquid chromatography- tandem mass spectrometry( UPLC- MS / MS) mehtod was developed to determine 18 quinolones in feeds. 18 quinolones were extracted by 0. 1% acetic acid- acetonitrile solution,cleaned up with SPE of HLB column and detected by UPLC- MS / MS. Quantitative results were based by isotope internal standard method. The calibration curve of 18 quinolones showed good linearity in the range of 0 ~1. 0 mg / L with conrrelation coefficient of 0. 9989 and 0. 9998 respectively. The detection limits of method were 0. 005 ~0. 2 mg / kg. The average recoveries of 18 quinolones at the spiked levels of 0. 1 ~ 5. 0 mg / kg in feeds ranged from43. 0% ~ 101% with relative standard deviation less than 11. 2%. Experiments showed that the method was sensitive,high efficiency and good anti- interference. The method adapted to the detection of 18 quinolones in feeds.
