[Study on the chemical constituents in roots and rhizomes of Ligularia duciforms].
OBJECTIVE
To study the chemical constituents in roots and rhizomes of ligularia duciforms.


METHODS
The compounds were isolated by column chromatography, the structures were identified by physicochemical properties and spectral analysis.


RESULTS
Six compounds were isolated and identified as caffeic acid (I), (E)-docosyl-3, 4-dihydroxycinnamate (II), (E)-docosyl 3-methoxy-4-hydroxyferulate (III, beta-amyrone (IV), beta-sitosterol (V), and daucosterol (VI).


CONCLUSIONS
All the compound were isolated for the first time from the plant, and the compound II and IV were isolated firstly from the genus Ligularia.
