title: [Studies on macrocyclic jatrophane diterpenes of Euphorbia kansui].
abstract: OBJECTIVE
  To study macrocyclic jatrophane diterpenes of Euphorbia kansui.
  
  
  METHODS
  The compounds were isolated and purified by various column chromatographic methods. Structures were elucidated by spectroscopic analyses.
  
  
  RESULTS
  Three macrocyclic jatrophane diterpenes were isolated from E. kansui and were characterized as kansuinin D1 (1), kansuinin D (2), kansuinin A (3).
  
  
  CONCLUSIONS
  Kansuinin D1 (1) was a new compound.
