title: Further casbane-type diterpenes from the soft coral Sinularia depressa.
abstract: OBJECTIVE
  To study the minor diterpenes from the soft coral Sinularia depressa
  
  
  METHODS
  The chemical constituents were isolated and purified by various chromatographic techniques, and the chemical structures, including absolute configuration, were established on the basis of detailed analysis of spectroscopic data and by literature comparison with the data of related known compounds.
  
  
  RESULTS
  A new casbane-type diterpene, 2-epi-10-hydroxydepressin (1), was isolated and identified.
  
  
  CONCLUSIONS
  Compound 1 is a new casbane-type diterpene.
