title: [Study on chemical constituents in roots and rhizomes of Ligularia duciforms II].
abstract: OBJECTIVE
  To study the chemical constituents in roots and rhizomes of Ligularia duciforms.
  
  
  METHODS
  90% ethanol extract was isolated and purified by silica gel and sephadex LH-20 column chromatography, the structures of compounds were identified by physicochemical properties and spectral analysis.
  
  
  RESULTS
  Nine compounds were isolated and identified as lupeol (1), isoscopoletin (2), isoline (3), duciformine (4), (2S, 3S, 4R)-sphinganine-(2'R)-delta5',6' (E)-2'-hydroxytetracosanoylamino (5), tetracosanoic acid (6), tetracosanoicacid glyceride (7), (E)-docosyl ferulate (8), (E)-docosyl caffeate (9).
  
  
  CONCLUSIONS
  Compounds 1, 2, 5-7 were isolated for the first time from this plant, and the compound 2, 5-7 were isolated firstly from the genus Ligularia.
