OBJECTIVE: To establish a method for the content determination of amygdalin in Lianhua qingwen capsule. METHODS: HPLC was performed on the column of Phenomenex Kinetex XB-C18 with mobile phase of acetonitrile-0.2% Phosphoric acid solution (6 ∶ 94,V/V)at a flow rate of 1.0 ml/min, the detection wavelength was 207 nm, column temperature was 30 ℃, and the injection volume was 10 μl. RESULTS: The linear range of amygdalin was 43.16-215.80 μg/ml (r=0.999 7); the limit of detection was 0.431 6 μg/ml,the limit of quantitation was 1.294 8 μg/ml; RSDs of precision, stability and reproducibility tests no more than 0.69%; recovery was 95.16%-100.49% (RSD=1.67%,n=9). CONCLUSIONS: The method is simple and rapid with high accuracy and well reproducibility, and can be used for the content determination of amygdalin in Lianhua qingwen capsule.
