This paper investigated the determination of arctiin content in Xiaoer Qingyan granules by high performance capillary electrophoresis (HPCE) method. The borax solution of 37.5 mmol concentration containing 12.5% methanol was chosen as buffer solution. The experiment was performed at a constant voltage of 16 kV and UV detection wavelength of 277 nm. The content of arctiin in Xiaoer Qingyan granules was 3.678mg/g (RSD=1.72%) (n=6). The recovery was in the range of 80.9%-113.4% (n=6). This method is suitable for the detection of the content of arctiin in Xiaoer Qingyan granules.
