Triterpenoid saponins from the roots of Aralia spinifolia.
Two new triterpenoid saponins named aralosides H[1] and J [2], along with four known triterpenoid saponins 3-6 were isolated from the roots of Aralia spinifolia. Their structures were determined as 3-O-beta-D-xylopyranosyl-(1-->2)-[beta-D-glucuronopyranosyl (1-->3)]-beta-D-glucopyranosyl-oleanolic acid [1], 3-O-alpha-L-arabinofuranosyl-(1-->4)-beta-D-glucuronopyranosyl- oleanolic acid 28-O-beta-D-galactopyranosyl ester [2], araloside A methyl ester [3], chikusetusaponin Ib [4], chikusetusaponin IV [5], and araloside A [6] on the basis of spectral and chemical data.
