| Abstract: | Five triterpene glycosides have been isolated from the leaves of Acanthopanax giraldii Harms (Araliaceae), which are elucidated as: hederagenin-3-O-α-L-rhamnopyranosyl (1→2) -α-L-arabinopyranoside ( Ⅰ ), hederagenin-28-α-L-rhamnopyranosyl- (1→4) -β -D-glu- copyranosyl-(1→6)-β -D-glucopyranosylester ( Ⅱ ), 3-O-α-L-arabinopyranosyl-hederagenin- 28-β -D-glucopyranosyl- ( 1→6 ) -β -D-glucopyranosylester ( Ⅲ ), 3-O-α-L-arabinopyranosyl- hederagenin-28-α-L-rhamnopyranosyl- ( 1→4 ) -β -D-glucopyranosyl- ( 1→6 ) -β -D-glucopyra-nosylester ( Ⅳ ) and 3-O-α-L-rhamnopyranosyl- (1→2) -α-L-arabinopyranosyl-hederagenin-28-α-L-rhamnopyranosyl-( 1→4 )-β -D-glucopyranosyl-( 1→6 )-β -D-glucopyranosylester ( Ⅴ ). All of them are reported in this genus for the first time. Perhaps the findings are valuable for chemotaxonomy of Acanthopanax genus. |
