Özet

Four new oleanane-type saponins, papyrioside LA-LD, were isolated from the leaves of Tetrapanax papyriferum. The structures of these new compounds were elucidated as 11 alpha-hydroxy-3,21-dioxo-olean-12-en-28-oyl-alpha-L-rhamnopyranosyl-( 1-->4)-(6-O-acetyl-beta-D-glucopyranosyl)-(1-->6)-beta-D-glucopyranoside, 11 alpha-methoxy-3,21-dioxo-olean-12 -en-28-oyl-alpha-L-rhamnopyranosyl-(1-->4)-(6-O-acetyl-beta-D-glucopyranosyl)-(1-->6)-beta-D-glucopyranoside, 3 alpha-hydroxy-11 alpha-methoxy-21-oxo-olean-12-en-28-oyl-alpha-L-rhamnopyranosyl-(1-->4)-(6-O-acetyl-beta-D-glucopy- ranosyl)-(1-->6)-beta-D-glucopyranoside and 21 alpha-hydroxy-11 alpha-methoxy-3-oxo-olean-12-en-28-oyl-alpha-L-rhamnopy- ranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopy-ranoside, respectively, on the basis of spectroscopic and chemical evidence.
