title: [Determination of notoginsenoside R1 in radix notoginseng by HPLC-ELSD].
abstract: OBJECTIVE
  To establish a method for the determination of notoginsenoside R1 in Radix Notoginseng.
  
  
  METHODS
  The HPLC-ELSD method was used for the determination. Chromatographic conditions: Shimpack CLC-ODS column(6.0 mm x 150 mm), acetonitrile-water(30:70) as the mobile phase, and Shimadzu LC-6A with SEDEX 55 ELSD detector.
  
  
  RESULTS
  The recovery rate is 101.57% and relative standard deviation 1.98%.
  
  
  CONCLUSIONS
  The method is reliable for the quality control of Radix Notoginseng.
