[Studies on chemical constituents from pine cone of Pinus armandii].
OBJECTIVE
To study chemical constituents from pine cone of Pinus annandii.


METHODS
The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral analysis.


RESULTS
Seven compounds were identified as sandaracopimaric acid (I), isodextropimaric acid (II), 12-hydroxyabietic acid (III), dehydroabietic acid (IV), 15-hydroxydehydroabietic acid (V), beta-sitosterol (VI) and daucosterol (VII).


CONCLUSIONS
Compounds I-IV were isolated from this plant for the first time.
