title: [Study on chemical constituents of the Ixeris chinensis].
abstract: OBJECTIVE
  To study the chemical constituents of the Ixeris chinensis .
  
  
  METHODS
  The constituents were isolated by silica gel column chromatography, HPLC and recrystallization and their structures were elucidated on the basis of spectral analysis.
  
  
  RESULTS
  Fifteen compounds were isolated and identified as Methyl-4-hydroxyphenylacetate (1), Daucosterol (2), Sitosterol (3), Luteolin-7-O-beta-D-glucoside (4), 15-hydroxy-2-oxoguaia-1 (10), 3,11 (13)-triene-12,6-lactone (5), Chinensiolide B (6), Chinensiolide E (7), Ixerochinoside (8), Chinensiolide C (9), 10alpha-hydroxy-guaia-4(15)-ene-12,6-lactone (10), 10alpha-hydroxy-guaia-4 (15), 11 (13)-diene-12,6-lactone-3beta-O-beta-D-(6'-p-hydroxyphenylacetyl) glucopyranoside (11), Epiloliolide (12), Apigenin-O-beta-D-glucopyranoside (13), Luteolin (14), Lutein (15).
  
  
  CONCLUSIONS
  Compounds 1,10,11,12 and 15 are isolated from this plant for the first time.
