title: [Chemical constituents of Juncus setchuensis].
abstract: OBJECTIVE
  To study the chemical constituents of Juncus setchuensis.
  
  
  METHODS
  Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.
  
  
  RESULTS
  Eight compounds were isolated and their structures were identified as 2-hydroxy-3-methylanthraquinone (1), physcion (2), stigmasterol (3), stigmast-3,6-dione (4), vanillin (5), n-heptacosanoic acid (6), trans-hydroxycinnamic (7) and 4-hydroxy-3-methoxy benzoic acid (8).
  
  
  CONCLUSIONS
  Compound 1, 2, 4 and 6 are obtained from this genus for the first time and all the compounds are obtained from this plant for the first time.
