Abstract
Two new compounds, a stigmasterol (1) and an eremophilenolide (2), were isolated from Ligularia dolichobotrys (Diels) together with ten known sesquiterpenoids, two known triterpenes and five known sterols. Their structures were elucidated by spectroscopic methods (IR, MS, 1H, 13C and 2D NMR). In addition, bakkenolide A (3) exhibited effective antitumor activity to human leukemia cells (HL-60), human hepatoma cells (Bel-7402) and human ovarian neoplasm cells (HO-8910).
