The paper investigated the determination of limited aritolonchic acid A content in Xinqin granules by capillary electrophoresis. The buffer was 30 mmol/L borax solution containing 3% ethanol. The voltage was 16 kV and UV detection wavelength was 250 nm. The aritolonchic acid A content in Xinqin granules was 2.87 mg/g(RSD=2.9%) (n=6). The recovery of aritolonchic acid A in Xinqin granules sample was in the range of 84.5%-126.7% (n=5). The average recovery was 105.9% (n=5). The new method is fit for the determination of limited aritolonchic acid A content in Xinqin granules.
