  • A new and two known lupane-triterpene glycosides were isolated from the hot MeOH fraction of the leaves of Acanthopanax gracilistylus W. W. Smith. Based on the physical properties and spectroscopic data, their chemical structures were determined as acankoreoside A (1), acankoreoside D (2), and $3{\alpha}-hydroxy-lup-23-al-20(29)-en-28-oic$ acid $28-O-{\alpha}-L-rhamnopyranosyl-(1{\rightarrow}4)-{$beta}-D-glucopyranosyl-(1{\rightarrow}6)-{\beta}-D-glucopyranosyl$ ester (3), respectively. To our best knowledge, compand 3 appears to be novel, which was named as wujiapioside A.

  • The effects of five lupane-triterpenoids from leaves of two Acanthopanax spp., chiisanogenin, chisanoside and $22{\alpha}-hydroxychiisanogenin$, acakoreoside A and acantrifoside A on the mitogen-induced proliferation were investigated in vitro. T cell proliferation (TCP) to concanavalin A (Con A) and the B cell proliferation (BCP) to lipopolysaccharide (LPS) were increased by chiisanogenin. TCP to Con A was significantly increased by chiisanoside and acankoreoside A, but not affected by chiisanogenin, $22{\alpha}-hydroxychiisanogenin$ and acantrifoside A, BCP to LPS was significantly increased by acankoreoside A and acantrifoside A, and slightly increased by chiisanoside, chiisanogenin and $22{\alpha}-hydroxychiisanogenin$.

  • Three known lupane-triterpenes, 3a-hydroxy-lup-20(29)-en-23,28-dioic acid (1), 3$\alpha$-hydroxylup-20(29)-en-23,28-dioic acid 28-Ο-$\alpha$-L-rhamnopyranosyl-(1$\rightarrow4)-\beta-D-glucopyranosyl-(1\rightarow6)-\beta$-D-glucopyranosyl ester (acankoreoside A, 2) and $3\alpha$, $11\alpha$-dihydroxy-23-oxo-lup-20(29)-en-28-oic acid (3) were isolated from the leaves of Brassaiopsis glomerulata (Blume) Regel, a species of Araliaceae family growing in Vietnam. Their structures were determined on the basis of spectroscopic data.

  • Two triterpenoids (1,4) and two triterpenoid glycosides (2,3) were isolated from the root of Acanthopanax koreanum (Araliaceae). Their structures were identified as impressic acid (1), acankoreoside A (2), 3-epi-betulinic acid 28-O-[(${\alpha}-L-rhamnopyranosyl(1{\rightarrow}4)-{\beta}-D-glucopyrano-syl(1{\rightarrow}6)]-{\beta}-D-glucopyranosyl]$ ester (3), and ursolic acid (4) by physicochemical and spectro-scopic methods. Of these compounds, impressic acid (1) exhibited a potent inhibitory activity against NFAT transcription factor ($IC_{50}:{\;}12.65{\;}{\mu\textrm{m}}$).
