Eleven new oleanane-type triterpenoid saponins, saniculasaponins I-XI (1-11), and a known saponin, sandrosaponin IX (12), were isolated from the methanol extract of the whole plants of Sanicula elataHam. var. chinensis Makino. The structures of the new compounds were elucidated on the basis of chemical and spectroscopic evidence.
