A new furost-20(22)-ene oligoglycoside named as aspacochioside C was isolated from the roots of Asparagus cochinchinensis (Lour.) Merr.. Its structure was elucidated to be 26-O-b- D-glucopyranosyl-(25S)-5b-furost-20(22)-en-3b,26-diol-3-O-a-L-rhamnopyranosyl-(14)-b-D- glucopyranoside on the basis of spectroscopic techniques including 1D and 2D NMR experiments.
