Abstract: Two new triterpenoid saponins named yiyeliangwanoside VII [1] and VIII [2], along with a known triterpenoid saponin liangwanoside II [3] were isolated from the alcoholic extract of the bark of Nothopanax davldii (Franch.) Harms (family Araliaceae). Their structures have been determined on the basis of spectral and chemical data as 3-O-β-(2',4'-O-diacetyl)-D-Xylopyrano-syl-3β-hydroxyolean-12-ene-28, 29-dioic acid-28-O-[α-rhamnopyranosyl (1-4)-β-D-glucopyano-syl (1-6)-β-D-glucopyranosyl] ester [1]; 3-O-β-(3'-O-acetyl)-D-xylopyranosyl-3β-hydroxyolean-12-ene-28,29-dioic acid-28-O-[α-L-rhamnopyranosyl (1-4)-β-D-glucopyranosyl (1-6)-β-D-glu-copyranosyl] ester [2]; 3-O-α-L-arabinopyranosyl-3β-hydroxyolean-12-ene-28, 29-dioic acid-28-O-[α -L-thamnopyranosyl (1-4)-β-D-glucopyranosyl (1-6)-β-D-glucopyranosyl] ester [3].
