Abstract:
Objective To establish a sensitive,valid and rapid high performance liquid chromatography-trap mass spectrometry (HPLC-MS) method for determining carbocisteine concentration in human plasma. Methods Plasma samples were pretreated by 100 mL/L perchloric acid to remove the interference protein. The supernatant was separated by reverse phase HPLC,electrospray MS was used to detect carbocisteine in plasma samples,and selective ion method of multiple reaction modes was used to determine the concentration of carbocisteine. Results The limit of detection was 0.01 ?g/mL and the linear range was 0.2-200.0 ?g/mL. The recovery rate was within the range of 89.2%-105.6%. Conclusion The proposed method could be used to determine carbocisteine in biological samples.
