In the course of phytochemical investigations of Ligularia vellerea rhizomes, a new naphthoquinone, 2,5-dihydroxy-6,7-dimethylnaphthoquinone (1), and a new neolignan, 4-[(3',4'-dihydroxycinnamoyl)-oxy]methyl cinnamate (2), have been isolated and characterized on the basis of spectroscopic methods (1H NMR, 13C NMR, 2D NMR, and MS).
在对 Ligularia vellerea 根茎进行植物化学研究的过程中,分离出了一种新的萘醌--2,5-二羟基-6,7-二甲基萘醌(1)和一种新的新木质素、4-[(3',4'-dihydroxycinnamoyl)-oxy]methyl cinnamate (2)),并根据光谱方法(1H NMR、13C NMR、2D NMR 和 MS)对其进行了表征。
