Abstract:
OBJECTIVE:To establish a method for the content determination of amygdalin in Lianhua qingwen capsule. METH-ODS:HPLC was performed on the column of Phenomenex Kinetex XB-C18 with mobile phase of acetonitrile-0.2%Phosphoric acid so-lution(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 injec-tion volume was 10μl. RESULTS:The linear range of amygdalin was 43.16-215.80 μg/ml(r=0.999 7);the limit of detection was 0.431 6μg/ml,the limit of quantitation was 1.294 8μg/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.
