La. Yakovishin et al., Triterpene glycosides of Hedera canariensis IV. Structures of glycosides L-F-3, L-G(0), and L-G(1a) from the leaves of Algerian ivy, CHEM NAT CO, 35(1), 1999, pp. 65-69
Three minor partially acetylated glycosides have been isolated from the lea
ves of Algerian ivy, Hedera canariensis Willd. (Araliaceae) - the previousl
y known {3-O-[alpha-L-rhamnopyranosyl-(1-->2)-O-alpha-L-arabinopyranoside]
28-O-[alpha-L-rhamnopyranosyl-(1-->4)-O-(6-acetyl-beta-D-glucopyranosyl)-(1
-->6)-O-beta-D-glucopyranoside}s of oleanolic acid and of hederagenin (ciwu
jianoside C-4 and kizuta saponin K-11) and the new 3-O-[alpha-L-rhamnoprano
syl-(1-->2)-alpha-O-L-arabinopyranoside] 28-O-[alpha-L-rhamnopyranosyl-(1--
>4)-O-(6-O-acetyl-beta-D-glucopyranosyl)-(1-->6)-O-beta-D-glucopyranoside o
f echinocystic acid (glycoside L-G(0)). The structures of the glycosides is
olated have been established on the basis of chemical transformations and H
-1 and C-13 NMR spectroscopy.
