摘要：

Further investigation of the leaves of Acanthopanax divaricatus gave two analogues of chiisanoside, which is a lupane triterpenoid oligoglycosyl ester. The structures were established as 28-O-alpha-L-rhamnopyranosyl(1 --> 4)-beta-D-glucopyranosyl( 1 --> 6)beta-D-glucopyranosyl esters of 1 beta,11 alpha-dihydroxy-3-oxo-lup-20(29)-en-28-oic acid and 1(R),11 alpha,22 alpha-trihydroxy-3,4-seco-lupa-4(23),20(29)-diene-3,28-dioic acid 3,11 alpha-lactone based on chemical and spectroscopic evidence. In biosynthetic terms, one is the precursor of chiisanoside and the other is an oxygenated derivative chiisanoside. (C) 1997 Published by Elsevier Science Ltd.
