Abstract
Three minor partially acetylated glycosides have been isolated from the leaves of Algerian ivy, Hedera canariensis Willd. (Araliaceae) — the previously known {3-O-[α-L-rhamnopyranosyl-(1→2)-O-α-L-arabinopyranoside] 28-O-[α-L-rhamnopyranosyl-(1→4)-O-(6-acetyl-β-D-glucopyranosyl)-(1→6)-O-β-D-glucopyranoside}s of oleanolic acid and of hederagenin (ciwujianoside C4 and kizuta saponin K11) and the new 3-O-[α-L-rhamnopyranosyl-(1→2)-α-O-L-arabinopyranoside] 28-O-[α-L-rhamnopyranosyl-(1→4)-O-(6-O-acetyl-β-D-glucopyranosyl)-(1→6)-O-β-D-glucopyranoside of echinocystic acid (glycoside L-G0). The structures of the glycosides isolated have been established on the basis of chemical transformations and1H and13C NMR spectroscopy.
