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).
Conclusion:
Compounds 1--6 are isolated from this plant for the first time.
