Abstract
Six triterpene saponins, including two new compounds, were isolated from the fruits of Hedera helix L. (Araliaceae). The structures of the new compounds, named helixosides A and B, were established as 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl hederagenin 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, and 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, respectively, on the basis of chemical and spectral data.
