Abstract: | From the BuOH extract of the whole plant of Ligularia virgaurea spp. oligocephala, a series of sesquiterpenes, sesquiterpene glycosides, and lignan glycosides were isolated, including the three new compounds (1α)‐1‐hydroxy‐8‐oxo‐eremophila‐6,9‐dien‐12‐oic acid ( 1 ), 8‐[(β‐D ‐glucopyranosyl)oxy]eremophila‐1(10),8,11‐trien‐2‐one ( 2 ), and 4‐[(β‐D ‐glucopyranosyl)oxy]pinoresinol ( 4 ). Their structures were elucidated by 1D‐ and 2D‐NMR as well as HR‐ESI‐MS analyses, and by comparison of the spectroscopic data with those reported for structurally related compounds. |
