目的:研究由食源性盐酸克伦特罗造成人体尿样兴奋剂检测阳性的可能性。方法:首先测定采用盐酸克伦特罗定量饲养的猪六个部位的肌肉组织中的盐酸克伦特罗含量,再使两名受试者进食烹饪熟的已知盐酸克伦特罗含量的猪肉及猪肝,最后检测受试者尿样是否呈克伦特罗阳性。检测猪肉及猪肝中克伦特罗采用液质联用法,检测受试者尿样中的克伦特罗采用兴奋剂常规方法——气质联用法。结果表明,单次食用猪肉制品中盐酸克伦特罗总量不超过1μg,则不会产生兴奋剂检测阳性。但服用克伦特罗一定残留量的动物组织会导致尿液克伦特罗阳性。
Aims: To investigate the possibility of positive human urine sample stimulants caused by food-grade clenbuterol. Methods: First, the content of clenbuterol in the muscle tissue of six pigs fed on a fixed dose of clenbuterol hydrochloride was measured, and two subjects were given cooking cooked pork of known clenbuterol content And pig liver, the final test subjects urine samples were clenbuterol positive. Determination of clenbuterol in pork and pork liver using liquid chromatography-mass spectrometry, test subjects urine clenbuterol stimulants conventional method - GC-MS. The results showed that the single consumption of pork products in the total amount of clenbuterol does not exceed 1μg, then the test does not produce doping positive. However, taking a certain amount of residual clenbuterol animal tissue will lead to clenbuterol urine.
