Triterpene saponins from the fruits of Hedera helix

Six triterpone saponins, including two new compounds, were isolated from th e fruits of Hedera helix L. (Araliacrae). The structures of the new compoun ds, named helixosides A and B, were established as: 3-O-beta-D-glucopyranos yl-(1 --> 2)-beta-D-glucopyranosyl oleanolic acid 28-O-beta-D-glucopyranosy l-(1 --> 6)-beta-n-glucopyranosyl ester, and 3-O-B-D-glucopyranosyl-( 1 --> 2)-beta D-glucopranosyl oleanolic acid 28-O-beta-D-glucopyranosyl-(1 --> 6 )-beta-D-glucopyranosyl ester, respectively, on the basis of chemical and s pectral data.
