title: [Lactone constituents of Saussurea involucrata].
abstract: OBJECTIVE
  To study the chemical constituents of Saussurea involucrata.
  
  
  METHODS
  Compounds were isolated and purified by column chromatography, and their structures were elucidated by chemical and spectroscopic methods.
  
  
  RESULTS
  Eight compounds were yielded and identified as beta-sitosterol (1), dotriacontanoic acid (2), hexacosan-4-olide (3), (+)-11alpha, 13-dihydrodehydrocostuslactone (4), 8alpha-acetoxydehydrocostus lactone (5), zaluzanin C (6), 11,13beta-dihydrozaluzanin C (7), 8alpha-hydroxy-11beta-11,13-dihydrodehydrocostuslactone (8).
  
  
  CONCLUSIONS
  Compounds 2-7 were first isolated from S. involucrate.
