				        	Object  To determine the amount of cichoric acid in Enchinacea purpurea and its preparation. Methods  By the use of HPLC, mobile phase: 400 mmol/L ammonium acetate  methanol   (95∶  5), flow rate: 1 mL/min, detection wavelength: 330 nm. Results  The mean recovery of cichoric acid was 99  41%, RSD=3  23% (n=5). Conclusion   The method can be applied in the determination of cichoric acid in E. purpurea extract and its preparation with satisfactory results.
