摘要: 研究了用快速分离柱高效液相色谱法测定肉中盐酸克伦特罗的方法。肉样品中的盐酸克伦特罗用水超声振荡提取,然后用固相萃取预分离和富集,以ZORBAX Stable Bound(4.6×50mm,1.8μm)C18快速分离柱为固定相,0.01mol/L的磷酸二氢钾水溶液:甲醇=65:35为流动相分离,流速为1.0ml/min;在该色谱条件下,盐酸克伦特罗在1.0min内可达到基线分离;用紫外二极管矩阵检测器检测。方法标准回收率为84%~98%,相对标准偏差为1.5%~2.5%。方法用于几种肉样品的测定,结果满意。

Abstract: A rapid column high performance liquid chromatography (HPLC) method for the determination of Clenbuterol Hydrochloride in meat was studied. The Clenbuterol Hydrochloride was extracted from the sample with water by ultrasonic extraction. Then the Clenbuterol Hydrochloride was purified and enriched by solid phase extraction. The Clenbuterol Hydrochloride was separated on a ZORBAX Stable Bound (4.6×50 mm, 1.8 μm) rapid chromatographic column with methanol and 0.01 mol/L KH2PO4 35:65 as mobile phase at a flow-rate of 1.0 ml/min, and monitored with the photodiode array detector at 243 nm. The recoveries of the Clenbuterol Hydrochloride were 84%~98%, and the relative standard deviations were 1.5%~ 2.5%. This method was being applied to the determination of Clenbuterol Hydrochloride in meat with good results.
