Three known lupane-triterpenes, 3alpha-hydroxy-lup-20(29)-en-23,28-dioic acid (1), 3a-hydroxylup-20(29)-en-23,28-dioic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (acankoreoside A, 2) and 3alpha,11alpha-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.
