    Journal: Yao Xue Xue Bao; 2004 May; 39(5):354-8. PubMed ID: 15338878.
    Abstract:
    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 newtriterpenoid 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-beta-D-glucopyranosyl 3beta,23-dihydroxylup-20 (29)-en-28-oic acid 28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (1), 3-O-beta-D-glucopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (2), 3-O-beta-D-glucopyranosyl 3beta-hydroxyolean-9(11),12-dien-28-oic acid 28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (3) and 3alpha-hydroxyolean-12-dien-23,28-dioic acid 28-O-alpha-L-rhamnopyranosyl (1 --> 4 )-beta-D-glucopyranosyl (1 --> 6)-beta-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.
