Method The analytes were extracted with NH 4 AC solution from samples and hydrolysised with beta-glucuronidase overnight at 37. The extract was filtered and the filtrate was cleaned by Oasis MCX solid phase extraction cartridge. Quantification of the 3 analytes was achieved by UPLC-MS/MS with multiple reaction monitoring (MRM) using internal standard method. Results The method had a good recovery for the clenbuterol, ractopamine, and salbutamol, and the correlation coefficient was more than 0.99 with the limit of quantitation (LOQ) 0.5 μg/kg. Conclusion The method is suitable for the determination of clenbuterol, ractopamine, and salbutamol residues in animal plasma.
