The key factors for separation and determination were studied and the best analysis conditions were obtained. In the buffer of 2.0 mmol/L HAc-3.0 mmol/L NaAc-10.0% CH 3OH at a separation voltage of 22 kV, Sinomenine in the sample could be separated and detected within 4 min. The linear mass concentration of Sinomenine is in the range of 1.0—36.0 μg/mL, the limit of detection reached 0.20 μg/mL.
