A new naphthoquinone and a new neolignan from Ligularia vellerea rhizomes


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).
