Target compounds were extracted with methanol and centrifuged. The supernatant was then transferred and concentrated, and applied to a solid phase extraction MCX cartridge for clean-up before UPLC analysis. The calibration curves for the four β-agonists were good linear in concentration range of 0.05-1.0μgmL−1 with the correlation coefficients (r) over 0.999. The average recoveries were in the range of 90.1-101.4% with relative standard deviation values lower than 8.0%.
