RESUMO
AIM@#To study the chemical constituents of the roots of Asparagus cochinchinensis (Asparagaceae).@*METHODS@#The compounds were isolated with Diaion HP20, silica gel, and ODS chromatography, and their structures were determined on the basis of chemical methods, HR-ESI-MS, and 1D- and 2D-NMR techniques.@*RESULTS@#Seven compounds were isolated from the n-butanol fraction of the roots of A. cochinchinensis, and their structures were elucidated as (25S)-26-O-β-D-glucopyranosyl-5β-furostan-3β, 22α, 26-triol-12-one-3-O-β-D-glucopyranoside (1), (25S)-26-O-β-D-glucopyranosyl-22α-methoxy-5β-furostan-3β, 26-diol-12-one-3-O-β-D-glucopyranoside (2), (25S)-26-O-β-D-glucopyranosyl-5β-furostan-3β, 22α, 26-triol (3), (25S)-26-O-β-D-glucopyranosyl-5β-furstan-3β, 22α, 26-triol-3-O-β-D-glucopyranoside (4), (25S)-26-O-β-D-glucopyranosyl-5β-furostan-3β, 22α, 26-triol-3-O-α-L-rhamnopyranosyl-(1, 4)-β-D-glucopyranoside (5), (25S)-5β-spirostan-3β-ol-3-O-α-L-rhamnopyranoside (6), and (25S)-5β-spirostan-3β-ol-3-O-β-D-glucopyranoside (7).@*CONCLUSION@#Compounds 1 and 2 were two new furostanol saponins.
