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).
Conclusion:
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.
