中文摘要 | 目的:建立测定蜂蜜中残留氯霉素的高效液相色谱-串联质谱方法,监测市场上蜂蜜中的氯霉素含量,保障蜂蜜的食用安全。方法:采用高效液相色谱-电喷雾-串联四极杆质谱法(HPLCESI~- -MSMS)测定蜂蜜中残留氯霉素的含量。取5g蜂蜜样品,加入d_5-氯霉素内标,经Oasis SPE柱净化,采用多反应检测(MRM)方式测定321152(氯霉素)和326157(d5-氯霉素)。结果:以321152离子面积与326157离子面积的比对氯霉素的浓度线性回归,线性范围为01~100ng·mL~(-1),r为0.9999。方法的检出限为0.02mug·kg~(-1),定量限对0.1mug·kg~(-1),日内和H间精密度实验的RSD分别为3.71%和4.19%,对0.2,5.0,40mug·kg~(-1)三个水平开展了加标回收实验。平均相对回收率分别为110%,103%,103%。结论:该方法操作简便、有机试剂用量少、结果准确、灵敏度高。 |
英文摘要 | Objective:A sensitive liquid chromatography tandem mass spectrometry (LC -MS/MS) method was developed to detect trace amounts of chloramphenicol residue in honey. Method:The mass spectrometer was operated in the negative ionization electrospray mode using multiple reaction monitoring(MRM) for quality and quantification analysis of chloramphenicol. Honey were spiked with isotopical label d_5 - chloramphenicol as internal standard. The method carried on an Oasis solid - phase extraction of aqueous honey solutions followed by liquid - liquid partitioning and direct injection to the LC -MS/MS system. Quantification of chloramphenicol is made by taking the ratio of the chloramphenicol base peak area (m/z 321152) to the internal standard d_5 - chloramphenicol base peak area(m/z 326157). Results:The limits of detection (LOD) was 0.020 mug·kg~(-1), and the limits of quantification (LOQ) was 0.100 mug·kg~(-1). The linear plots were obtained between 0.10and 100 ng · mL~(-1) and CV is 0.9999. Overall recoveries was between 103 % and 110%. Conclusion:The advantages of the method are simple operation, less organic chemicals consumed, and shorter operation time. |
