Objective:To establish an HPLC method to check lornoxicam related substances and hazardous material 2-aminopyr-idine. Methods:The C18 column was adopted with the mobile phase of 0.025 mol·L-1 ammonium dihydrogen phosphate solution-methanol (58:42) (triethylamine adjusted to pH 7.3) at the flow rate of 1.0 ml·min-1, and the detection wavelength was 290nm, column temperature:30℃. Results:2-aminopyridine, lornoxicam and relevant materials to achieve an effective separation method durability was good. The LOD of lornoxicam was 2.006ng, The LOD of 2-aminopyridine was 0.5045ng, The LOQ of 2-aminopyridine was 1.009 ng. The linear ranges of 2-aminopyridine was 0.100μg·mL-1~1.009μg·mL-1 (r=0.9997). The average recovery of 2-amino-pyridine was 106.5%(RSD=3.2%). Conclusion:The method was simple, stable, specific, and could be used lornoxicam related sub-stances, and 2-aminopyridine checks.
