| Abstract: | The structures of two new triterpene glycosides, L-E2 and L-H3 from the leaves of Algerian ivyHedera canariensis Willd. (fam. Araliaceae), have been established on the basis of chemical and spectral characteristics: they are 30-norhederagenin
3-O-α-L-rhamnopyranosyl-(1→2)-O-α-L-arabinopyranoside and the 28-O-α-L-rhamnopyranosyl-(1→4)-O-β-D-gentiobiosyl ester of 30-norhederagenin 3-O-α-L-rhamnopyranosyl-(1→2)-O-α-L-arabinopyranoside, respectively.
