摘　　要：为了解我国食品检测实验室的β-受体激动剂检测能力,CNAS于2010年委托中国兽医药品监察所组织实施了猪肝中克仑特罗、沙丁胺醇和莱克多巴胺三种β-受体激动剂残留检测的能力验证工作。全国22个省、市、自治区的共68个实验室参加了本次能力验证,采用的测试方法主要是液相色谱-串联质谱法(LC-MS/MS)和气相色谱-质谱法(GC-MS)。结果显示:克仑特罗、沙丁胺醇和莱克多巴胺的实验室满意结果率分别为77.8%、89.6%和92.2%,可疑结果率分别为11.1%、4.17%和0,不满意结果率分别为11.1%、6.25%和7.84%,说明参加能力验证的绝大多数实验室可以准确检测以上三种β-受体激动剂残留。In order to understand the capability of food testing labs in China for β-agonists testing,the CNAS delegated China Institute of Veterinary Drug Control to organize the proficiency testing（PT） of determination of clenbuterol,salbutamol and ractopamine residues in pig liver（CNAS T0509）.68 labs from 22 provinces/cities/municipalities took part in the PT.LC-MS/MS and GC-MS methods were adopted.The PT showed that 77.8%,89.6% and 92.2% labs had satisfactory results,11.1%,4.17% and 0 labs had questionable results;11.1%,6.25% and 7.84% labs had dissatisfactory results for clenbuterol,salbutamol and ractopamine,respectively.In conclusion,the most labs taken part in the PT have good competence in analyzing the three kinds of β-agonists.
