Abstract:
Objective To establish a method for determination of the content of Forsythoside A in Yinqiaosan granules . Methods HPLC method was adopted to carry on the determination .Welch Ultimate XB‐C18 column (250 mm × 4 .6 mm ,5μm) was used with the mobile phase of methanol‐0 .2% Glacial acetic acid solution by gradient elution . The flow rate was 1 .0 ml/min ,the detection wavelength was 330 nm ,and the column temperature was 20 ℃ .Results Forsythoside A showed a good linear relationship at the range from 0 .080 3~3 .211 μg (r=1 .000) .The average recovery rates were 103 .78% ,and RSD=0 .82% .Conclusion The method was convenient and accurate .Meanwhile ,it also has good specificity and reproducibili‐ty .It can be used effectively for the quality control of Yinqiaosan granules .
