Three new lupane-type saponins, acankoreosides F--H (1--3) were isolated from the methanol extract of the leaves of Acanthopanax koreanum NAKAI. The structures of these three saponins were established by chemical and spectroscopic analysis as 3alpha,30-dihydroxylup-20(29)-en-23,28-dioic acid 28-O-[alpha-L-rhamnopyranosyl-(1--&gt;4)-beta-D-glucopyranosyl-(1--&gt;6)-beta-D-glucopyranosyl] ester (1), 3alpha,30-dihydroxylup-23-al-20(29)-en-28-oic acid 28-O-[alpha-L-rhamnopyranosyl-(1--&gt;4)-beta-D-glucopyranosyl-(1--&gt;6)-beta-D-glucopyranosyl] ester (2), and (20S) 3alpha-hydroxylup-23-al-28,29-dioic acid 28-O-[alpha-L-rhamnopyranosyl-(1--&gt;4)-beta-D-glucopyranosyl-(1--&gt;6)-beta-D-glucopyranosyl] ester (3), respectively. The effects of the isolates (1-3) on the lipopolysaccharide-induced production of nitric oxide and prostaglandin E2 were evaluated in RAW 264.7 macrophages.
