Abstract: The new pyrrolizidine alkaloid glycoside 1, and the three new highly oxygenated bisabolane sesquiterpenes 4–6, together with the two known pyrrolizidine alkaloids 2 and 3, were isolated from the roots of Ligularia cymbulifera (W. W. smith) hand.‐mazz. Their structures were established on the basis of spectroscopic analysis, especially 1D‐ and 2D‐NMR data. The cytotoxic activities of compounds 1, 2, and 4–6 were evaluated against hepatoma (BEL‐7402), human leukemia (HL‐60), human ovarian carcinoma (HO‐8910), and nasopharyngeal carcinoma (KB) cell lines (Tables 1–3). Compound 6 showed weak cell‐growth inhibition of BEL‐7402 cell.
