Abstract：Objective:To establish the identification and content determination methods of Qi Feng Er Teng Granules.Methods:TLC was used for identification and HPLC was used for content determination.Results:The TLC method allowed effective identification of all crude drugs in the formulation.The calibration curves of pae-oniflorin,prim-O-glucosylcimifugin,calycosin-7-glucoside,5-O-methylvisammioside,icariin,sinomenine,and as-tragaloside IV showed good linearity in the range of 9.01～45.1,1.69～8.44,1.04～5.20,1.32～6.59,4.35～21.7,13.5～67.5,101～506 μg·mL-1,respectively.The average recovery rate of sample addition was within the range of 95.0%to 105.0%(RSD<3.2%).Conclusion:The TLC and HPLC methods established in this study for Qi Feng Er Teng Granules have strong specificity,high sensitivity and good reproducibility,and can be used for the quality control of Qi Feng Er Teng Granules.
