title: A new eudesmane sesquiterpenoid lactone from Chloranthus japonicus.
abstract: OBJECTIVE
  To study the chemical constituents of the whole plant of Chloranthus japonicus.
  
  
  METHODS
  Compounds were isolated and purified by column chromatography. Their structures were elucidated on the basis of spectroscopic methods.
  
  
  RESULTS
  Six sesquiterpenoids were obtained and their structures were identified as chlojaponilactone A (1), atractylenolide III (2), neolitacumone B (3), 10α-hydroxy-1-oxoeremophila-7(11), 8(9)-diene-8, 12-olide (4), shizukanolide C (5), and shizukanolide H (6).
  
  
  CONCLUSIONS
  Compound 1 is a new eudesmane-type sesquiterpenoid lactone, and compounds 3 and 4 have been isolated from this species for the first time.
