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


METHODS
90% ethanol extract was isolated and purified by silica gel and sephadex LH-20 column chromatography, the structures of compounds were identified by physicochemical properties and spectral analysis.


RESULTS
Nine compounds were isolated and identified as lupeol (1), isoscopoletin (2), isoline (3), duciformine (4), (2S, 3S, 4R)-sphinganine-(2'R)-delta5',6' (E)-2'-hydroxytetracosanoylamino (5), tetracosanoic acid (6), tetracosanoicacid glyceride (7), (E)-docosyl ferulate (8), (E)-docosyl caffeate (9).


CONCLUSIONS
Compounds 1, 2, 5-7 were isolated for the first time from this plant, and the compound 2, 5-7 were isolated firstly from the genus Ligularia.
