title: [Chemical constituents from capitula of Eriocaulon australe ].
abstract: OBJECTIVE
  To study the chemical constituents from the capitula of Eriocaulon australe.
  
  
  METHODS
  The compounds were isolated and purified by column chromatography and their structures were determined through spectroscopic techniques (NMR)and physicochemical properties.
  
  
  RESULTS
  Six compounds were identified from capitula of Eriocaulon australe as (R)-semixanthomegnin( 1) ,tora-lactone-9-0-β-D-glucopyranoside(2), ( - ) -semivioxanthin-9-0-β-D-glucopyranoside( 3) ,4-ketopinoresinol(4) ,β-daucosterol (5) and 3,3'-dihydroxy-4,4'-dimethoxybiphenyl(6).
  
  
  CONCLUSIONS
  Compounds 1 ~ 6 are isolated from this plant and compounds 3 ~ 6 are ob- tained from Eriocaulon genus for the first time. Compound 1 shows DNA scission activity.
