Determination of Forsythin in Xiaoerjinqiao Granules by HPLC

Objective: To establish a method to determine the content of Forsythin in Xiaoerjinqiao Granules. Methods: High performance liquid chromatography （HPLC）was applied with the condition of 0.1% phosphoric acid-acetonitrile as mobile phase for gradient elution, the flow rate was 1.0 mL/min, the detection wavelength was 277 nm. Results: The calibration curve was linear in the range of 0.5-5.0 μg for Forsythin, r=0.999 9; the average recovery was 99.3%, and relative standard deviation RSD=0.25%（n=6）.Conclusion: The established method is accurate and reliable, and can be used to determine the Forsythin in Xiaoerjinqiao Granules.
