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-α-l-rhamnopyranosyl(1→4)-β-d-glucopyranosyl(1→6)β-d-glucopyranosyl esters of 1β,11α-dihydroxy-3-oxo-lup-20(29)-en-28-oic acid and 1(R),11α,22α-trihydroxy-3,4-seco-lupa-4(23),20(29)-diene-3,28-dioic acid 3,11α-lactone based on chemical and spectroscopic evidence. in biosynthetic terms, one is the precursor of chiisanoside and the other is an oxygenated derivative chiisanoside.
