Abstract:
AIMTo study the chemical constituents of Ligularia dictyoneura.
METHODSVarious chromatographic techniques were used to separate and purify the compounds. Their spectral data (MS, IR, NMR) were measured for structure elucidation.
RESULTSFour sesquiterpenes were isolated from Ligularia dictyoneura and their structures were identified as ligudicin A (1), ligudicin C (2), ligudicin D (3) and isopetasin (4).
CONCLUSIONCompound 1 is a new compound, compound 2 is a new natural product, and compounds 3 and 4 are obtained from Ligularia dictyoneura for the first time.
