| Abstract: | OBJECTIVE To study the chemical constituents of Ligularia dictyoneura. METHODS Various chromatographic techniques were used to separate and purify the constituents. Tlieir spectral data (MS, IR and NMR) were obtained for structure elucidation. RESULTS Four compounds were isolated from Ligularia dictyoneura and their structures were identified as 8p-hydroxyeremophil-7(11)-en-12, 8a-olide (I)，3, 3',4'，7-tetramethoxyflavone (E), 3, 3',7-trihydroxy-4'-methoxyflavone (Ⅲ), β-sitosterol (IV). CONCLUSION Compound I is a new natural product. Compounds Ⅱ and Ⅲ are obtained from genus Ligularia for the first time. |
