Title: Study on Quality Standard of Huayu Qutan Granules
Abstract: Objective To establish the quality control standard of Huayu Qutan granules.Methods The TLC method was applied to identify Codonopsis pilosula,Astragalus mongholicus,Fiveleaf Gynostemma Herb and Curcuma aromatica.The content of Salvianolic acid B was determined by HPLC.Experiment was carried out on Diamonsil C18 column with mobile phase consisted of methanol-acetonitrile-methane acid-water(30︰10︰1︰59) at a flow rate of 1.0 mL/min.The detection wavelength was at 286 nm and the column temperature was 30 ℃.Result The TLC spots were clear and distinguished well,and the negative sample didn’t interfere the identification of TLC.Salvianolic acid B showed a good linear relationship with its peak area in the range of 0.142 5-1.425 0 μg(r =0.999 7).The average recovery rate was 98.45% and RSD was 1.99%.Conclusion The method is reliable,specific and reproducible,so it can be used for quality control of Huayu Qutan granules.
