abstract: OBJECTIVE
  To determine ginsenoside Rg1, Re, Rb1, Rc, Rb2, Rd from main root and root hair of red ginseng of different specifications.
  
  
  METHODS
  Ultrasonical extraction and reversed phase high performance liquid chromatography were applied.
  
  
  RESULTS
  The total contents of six ginsenosides from main root 15 roots (percent 500 g), 20 roots, 30 roots and root hair are 1.21%, 1.46%, 1.54% and 8.16%, respectively.
