Abstract
This paper investigated the determination of amygdalin content in Lianhua Qingwen Granules by high performance capillary electrophoresis (HPCE) method. The borax solution of 20 mmol concentration containing 15% methanol was chosen as buffer solution. The experiment was performed at a constant voltage of 18kV and UV detection wavelength of 210 nm. The content of amygdalin in Lianhua Qingwen Granules was 9.906 mg/g (RSD = 3.8%) (n = 7). The recovery was in the range of 79.1% - 122.3% (n=6). This method is suitable for the detection of the content of amygdalin in Lianhua Qingwen Granules.
