Abstract: | Objective: To establish a method for determination of Caffeic acid in Kuanxiong Shuqi Huazhi Pill. Method: HPLC analysis was carried out using ODS column (4. 6 mm ×250 mm, 5μm) and acetonitrile -0. 04% phosphoric acid (11: 89) as the mobile phase. The detection wavelength was 325 nm,the flow rate was 1.0 mL · min^-1 ,the column temperature was 40 ℃. Results: The liner range was 0. 051 6 - 1. 032 μg ( r = 0. 999 9 ). An average recovery of 100. 57% ( n = 6 ) was obtained with RSD 1. 75% . Conclusion: The method is simple, accurate and suitable for the qualify control. |
