Aim Isolation and structural elucidation of the triterpenoid saponins of Oplopanax elatus
Nakai. Methods Solvent extraction and column chromatography were used to isolate the triterpenoid saponins,
physico-chemical constants and spectroscopic analysis were employed for structural elucidation. Results Four
new triterpenoid saponins named cirenshenoside S(1), cirenshenoside T(2), cirenshenoside U(3) and
cirenshenoside V(4) were isolated, and their structures were elucidated to be 3-O-β-D-glucopyranosyl 3β,23-
dihydroxylup-20 (29)-en-28-oic acid 28-O-α-L-rhamnopyranosyl (1→4)-β-D-glucopyranosyl(1→6)-β-D-
glucopyranoside(1), 3-O-β-D-glucopyranosyl hederagenin 28-O-α-L-rhamnopyranosyl (1→4)-β-D-
glucopyranosyl (1→6)-β-D-gtucopyranoside (2), 3-O-β-D-glucopyranosyl 3β-hydroxyolean-9(11), 12-dien-28-
oic acid 28-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→6)-β-D-glucopyranoside (3) and 3α-
hydroxyolean-12-dien-23,28-dioic acid 28-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl (1→6)-β-D-
glucopyranoside(4), respectively. Conclusion Compounds 1-4 are new triterpenoid saponins and isolated
from the leaves of Oplopanax elatus Nakai for the first time.
