Abstract

A new lupane-type saponin, named acankoreoside E (1), was isolated from the methanol extract of the leaves of Acanthopanax koreanum, and its structure was established through chemical and spectroscopic analyses as (20S) 3α-hydroxy-30-oxolupan-23,28-dioic acid 28-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester.
