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.
