Abstract: | OBJECTIVE: To establish a method for determining Chlorogenic Acid in Flos Lonicera Japonica Extract. METHODS: A Kromasil C18 column (4.6 mm x 150 mm, 5 μm) with acetonitrile -0.4% H3PO4 (15:85)as the mobile phase was used for determination, the flow rate was 1.0 mL· min ^-1 and the UV detection wavelength was at 327 nm. RESULTS:There was a good linear relationship at a range of 0. 106 - 1.016 μg for Chlorogenic Acid (r = 0.999 9), the average recovery rate was 100.3 % with RSD of 1.04 % (n = 6). CONCLUSION:The results indicate that the HPLC method is simple, accurate, highly selective and reproducible, thus it could be used as quality control in the preparation of Flos Lonicera Japonica Extract. |
