Objective: To determine atractylodin in ermiao pill to provide scientific basis for its quality control. Method :A kromasil C18 (4.6 mm×150 mm
5 μm) liquid chromatographic column was used. The mobile phase was alcohol -water.Walvelength was at 340 nm. Result :The linear range of atractylodin was within 42.2-675.0 mg·L-1(r=0.999 7)
sample recovery rate was 99.18%
RSD 1.49%. Conclusion :This method has good repeatabilityand flexibility. It can be used for quality control in production of ermiao pill.
