Two new triterpenoid saponins isolated from the root bark of Heinsia crinata were characterized as heinsiagenin A-3 beta-O-(beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 6)-[alpha-L-rhamnopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside) and heinsiagenin A-3 beta-O-(alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranosyl(1 --> 2)-beta-D-glucopyranoside). The structures were deduced mainly from a combination of 1- and 2D NMR experiments.
