Abstract:: Taking Trdllius chinensis Bunqe as material，anions were extracted by ultrasonic method，and F^-，Cl^-，NO₃^-，SO₄^2-in Trdllius chinensis were determinated by ion-chromatography.The results showed that 4 anions in the samples were extracted ultrasonically with water for 20 min，at 80℃.The separation of 4 anions was performed on IonPac AS14A analytic column with an eluent containing 8 mmol/L Na₂CO₃+1 mmol/L NaHCO₃，and the flow rate as 1.00 mL/min.The correlation coefficients were superior to 0.999，and the recoveries were 89.70%~105.35%，the detection limits of these anions were in the range of 0.02~0.04 mg/L.The method was simple and accurate and could be applied in the analysis of Trdllius chinensis samples.
