title: [Simultaneous Determination of Five Astragalosides in Astragali Radix and Jinqi Jiangtang Tablet by HPLC-ELSD].
abstract: OBJECTIVE
  To develop an HPLC-ELSD method for simultaneous determination of Astragaloside IV Astragaloside I, Astragaloside II, Astragaloside III and Isostragaloside II in Astragali Radix and Jinqi Jiangtang tablet.
  
  
  METHODS
  The chromatographic conditions were as follows: Grace Apollo C18 column (250 mm x 4. 6 mm, 5 µm), acetonitrile (A) and water(B) as mobile phases for gradient elution, and the flow rate being 1. 0 mL/min.
  
  
  RESULTS
  Five components showed good linearity. The average recoveries were between 95% - 105%. Five Astragalosides were determined in twelve batches of Astragali Radix and ten batches of Jinqi Jiangtang tablet.
  
  
  CONCLUSIONS
  This is a specific, sensitive and simple method for simultaneous determination of Astragaloside IV, Astragaloside I Astragaloside II, Astragaloside III and Isostragaloside II in Astragali Radix and Jinqi Jiangtang tablet.
