Objective To establish a method for the determination of haloperidol residues in milk by high performance liquid chromatography. Methods The samples was extracted with acidified acetonitrile (0.2% formic acid, V:V), purified by C18 solid phase extraction column, concentrated by nitrogen blowing, filtered by 0.45 μm filter membrane, separated by Agilent ZORBAX SB-C18 column with the acetonitrile-0.2% formic acid aqueous solution (1:1, V:V) as mobile phase and isometric elution was performed at 0.3 mL/min, and quantified by external standard method. Results The selected ultraviolet detection wavelength was 254 nm, under this condition, the linear relationship between haloperidol concentration (X, μg/mL) and peak area (Y) was good in the range of 0.2?5.0 μg/mL, the correlation coefficient was 0.999, and the spiked recoveries at 3.0, 7.0, 10.0 μg/mL were 81.73%?95.57%, the relative standard deviation was 1.97%, the limit of detection was 7.58 μg/L, and limit of quantification was 25.27 μg/L. Conclusion This method has the advantages of low cost, simple operation, strong operability, high recovery, high sensitivity and high accuracy, which is suitable for the detection of haloperidol in milk. |
