Article abstract of DOI:10.1016/0031-9422(82)83046-X

From the methanol extract of the fruits of Asparagus adscendens sitosterol-β-D-glucoside, two spirostanol glycosides (asparanin A and B) and two furostanol glycosides (asparoside A and B) were isolated and characterized as 3-O-<β-D-glucopyranosyl (1->2)-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-<<β-D-glucopyranosyl(1->2><α-L-rhamnopyranosyl(1->4)>-β-D-glucopyranosyl>-(25S)-5β-spirostan-3β-ol, 3-O-<<β-D-glucopyranosyl(1->2)><α-L-rhamnopyranosyl(1->4)>-β-D-glucopyranosyl>-26-O-(β-D-glucopyranosyl)-22α-methoxy-(25S)-5β-furostan-3β,26-diol and 3-O-<<β-D-glucopyranosyl(1->2)><α-L-rhamnopyranosyl(1->4)>-β-D-glucopyranosyl>-26-O-(β-D-glucopyranosyl)-(25S)-5β-furostan-3β,22α,26-triol, respectively.Key Word Index - Asparagus adscendens; Liliaceae; saponins; spirostarol glycosides; furostanol glycosides.
