title: [Determination of eight kinds of ginsenosides in Shizhu ginseng].
abstract: OBJECTIVE
  To establish the method for determining simultaneously eight kinds of ginsenoside Rg1, Re, Rf, Rg2, Rb1, Rc, Rb3 and Rd and their contents in Shizhu ginseng.
  
  
  METHODS
  HPLC was carried out on Agilent TC-C18 (4.6 mm x 150 mm, 5 microm) with acetonitrile -0.05% phosphoric acid, gradient elution, the volume of flow 1 mL x min(-1), column temperature 30 degrees C and detection wavelength 203 nm.
  
  
  RESULTS
  The contents of eight kinds of ginsenosides in Shizhu ginseng were 1.32, 2.08, 0.72, 0. 24, 2.12, 1.06, 0.35, 0.55 mg x g(-1), respectively.
  
  
  CONCLUSIONS
  The contents of ginsenoside ingredients in Shizhu ginseng were determined in the first time. The established method can be used in determining the contents of multiple gensenosides in herb ginseng simultaneously.
