Article abstract of DOI:10.1016/S0031-9422(00)80399-4

Two oligofurostanosides and two spirostanosides, isolated from a methanol extract of Asparagus adscendens (leaves), were characterized as 3-O-<<α-L-rhamnopyranosyl(1->4)><α-L-rhamnopyranosyl(1->6)-β-D-glucopyranosyl>-26-O-<β-D-glucopyranosyl>-22α-methoxy-(25S)-furost-5-en-3β,26-diol (Adscendoside A), 3-O-<<α-L-rhamnopyranosyl(1->4)><α-L-rhamnopyranosyl(1->6)>-β-D-glucopyranosyl>-26-O-<β-D-glucopyranosyl>-(25S)-furost-5-en-3β,22α,26-triol (Adscendoside B), 3-O-<<α-L-rhamnopyranosyl(1->6)>-β-D-glucopyranosyl>-(25S)-spirostan-5-en-3β-ol (Adscendin A) and 3-O-<<α-L-rhamnopyranosyl(1->4)><α-L-rhamnopyranosyl(1->6)>-β-D-glucopyranosyl>-(25S)-spirostan-5-en-3β-ol (Adscendin B), respectively.Adscendin B and Adscendoside A are the artefacts of Ascendoside B formed through hydrolysis and methanol extraction respectively.Key Word Index - Asparagus adscendens; Liliaceae; saponins; oligofurostanosides; spirostanosides.
