Seven new oleanane-type saponins, named araliasaponins XII-XVIII, were isolated from the roots ofAralia chinensis , together with 14 known triterpene saponins. On the basis of the chemical and spectroscopic evidence, the structures of these new saponins were elucidated as follows: 3-O-β-d-glucopyranosyl(1 -> 3)-[β-d-glucopyranosyl(1 -> 2)]-α-l-arabinopyranosyl oleanolic acid 28-O-β-d-glucopyranosyl...
Seven new oleanane-type and four new ursane-type triterpene saponins, named araliasaponins I-XI were isolated from the roots of Aralia decaisneana, together with four known triterpene saponins. On the basis of the chemical and spectroscopic evidence, the structures of these new saponins were elucidated as follows: 3-O-β-d-xylopyranosyl-(1 → 3)-β-d-glucopyranosyl-(1 → 3)-[β-d-xylopyranosyl-(1 → 2)]-α-l-arabinopyranosyl...
