Four new triterpenoid saponins, named as cirenshenosides S(1), T(2), U(3) and V(4), were isolated from the leaves of Oplopanax elatus Nakai. Their structures were elucidated to be 28-O-α-L-rhamnopyranosyl(1 → 4)- β- D-glucopyranosyl (1 → 6)- β- D-glucopyranosyl esters of 3 β ,23-dihydroxylup-20(29)-en-28-oicacid3-O- 13- β- -D- glucopyranoside(1), hederagenin3-O- β -D-glucopyranoside(2), 3 β -hydroxyolean-9(11), 12-dien-28-oic acid 3-O-β -D-glucopyranoside(3), 3 α-hydroxyolean- 12-en-23,28-dioic acid(4), respectively. |
