La. Yakovishin et al., Triterpene glycosides from Hedera canariensis. VI. Structure of L-G(1), and L-G(1b) glycosides from leaves of canary ivy, CHEM NAT CO, 35(5), 1999, pp. 543-546
Two new minor triterpene glycosides L-G(1') and L-G(2b) the 3-O-alpha-L-ara
binopyranosyl-28-O-alpha-L-rhamnopyranosyl-(1-->4)-O-beta-D-gentiobiosyl an
d 3-O-alpha-L-rhamnopyranosyl-(1-->2)-O-alpha -L-arabinolpyranosyl 28-O-alp
ha-L -L-rhamnopyranosyl-(1-->4)-O-(6-O-acetyl-beta-D-glucopyranosyl)-(1-->6
)-O-beta-D-glucopyranosyl esters of 30-norhederagenin , respectively are is
olated from the leaves of canary ivy (Hedera canariensis Willd.). The struc
tures of the glycosides are found by chemical methods and H-1 and C-13 NMR
spectroscopy.
