title: [Isolation and identification of diterpenoids from Pinus koraiensis].
abstract: OBJECTIVE
  To study chemical compounds from Pinus koraiensis.
  
  
  METHODS
  The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral alanlysis.
  
  
  RESULTS
  Eight compounds were identified as 8 (14)-podocarpen-13-on-18-oic acid (1), 15-hydroxydehydroabietic acid (2), 12-hydroxyabietic acid (3), lambertianic acid (4), dehydroabietic acid (5), sandaracopimaric acid (6), beta-sitosterol (7), daucosterol (8).
  
  
  CONCLUSIONS
  Compounds 1--6 are isolated from this plant for the first time.
