[Studies on the constituents from Cacalia ambigua].
OBJECTIVE
To study the constituents of Cacalia ambigua.


METHODS
The chemical constituents were isolated from the plant by all kinds of column chromatographies and their structures were identified by spectral methods.


RESULTS
Four compounds were isolated and identified as ent-kaur-16-en-19-oic acid (1), 13-beta-Kaur-16 beta-ol (2), beta-sitosterol (3) and 1-glyceryl nonadecanoic acid ester (4).


CONCLUSIONS
Compounds 1-4 are isolated from this plant for the first time, and compounds 1 and 2 and isolated from this genus for the first time.
