title: [Studies on the chemical constituents from the roots of Kalopanax septemlobus].
abstract: OBJECTIVE
  To investigate the chemical constituents of Kalopanax septemlobus.
  
  
  METHODS
  Chromatographic techniques including silica gel, gel, semi-preparative HPLC and PTLC as well as recrystallization were employed in the isolation and purification, and the structures were elucidated by spectral analysis and physical and chemical properties.
  
  
  RESULTS
  6 compounds were identified as liriodendrin (1), (-) -syringarenol (2), trans-coniferyl aldehyde (3), trans-caffeic acid (4), beta-daucosterol (5), beta-sitosterol (6).
  
  
  CONCLUSIONS
  Compounds 2 -5 are obtained from this genus for the first time.
