Abstract:Objective: To establish a method for detecting Rosmarinic acid in Xiasangju Granules with HPLC. Methods: The chromatographic column of Agilent ZORBAX SB C18 (4. 6 mm × 250 mm, 51m ) was used, the mobile phase was consisted of ace- tonitrile-0. 1% phosphoric acid aqueous solution (20: 80), The flow rate was 1.0 ml/min, the detective wavelength was 330 nm and the column temperature was 30℃ Results: The linear range of the method was 0. 068 - 1. 357μg ( r = 0. 999 9, n = 6), the average recovery was 99. 15%, RSD was 1.4% (n = 9). Conclusion: The results showed this method is accurate, reproducible, simple and easy to do, which can be used in quality control of Xiasangju Granules.
Keywords:Xiasangju Granules  Rosmarinic acid  HPLC
