[Isolation and identification of diterpenoids from Pinus koraiensis].

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.
