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 glucopyranosyl ( 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 glucopyranosylester(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.
