A new oleanane triterpene saponin 1 was isolated from Ligularia veitchiana. The structure of compound 1 was elucidated as olean-12-en-6β,16β,28-triol 3-O-β-D-glucuronopyranoside by spectroscopic data (1H, 13C NMR, HMBC, HSQC, COSY, and NOSEY) and chemical evidence. Additionally, compound 1 presented phytotoxic effect on the growth of lettuce at 200 ppm.
