Vi. Grishkovets et al., Triterpenoid glycosides of Fatsia japonica. II. Isolation and structure ofglycosides from the leaves, CHEM NAT CO, 36(5), 2000, pp. 501-505
The previously known triterpenoid 3-O-alpha -L-arabinopyranosides of oleano
lic and echinocystic acids and hederagenin, 3-O-beta -D-glucopyranosyl-(1 -
->2)-O-alpha -L-arabinopyranosides of oleanolic acid and hederagenin, in ad
dition to 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-O-beta -D-glucopyranosyl-(
1-6)-O-beta -D-glucopyranosyl ethers of the 3-O-alpha -L-arabinopyranoside
of hederagenin, and 3-O-beta -D-glucopyranosyl-(1 -->2)-O-alpha -L-arbinopy
ranosides of oleanolic acid and hederagenin, respectively, are isolated fro
m leaves of Fatsia japonica (Araliaceae). The structures of the glycosides
are confirmed by chemical Methods and (CNMR)-C-13 spectroscopy.
