Timosaponin A-III, the crystalline steroid saponin isolated from a commercial crude drug Timo (Anemarrhenae Rhizoma), has been shown to be sarsasapogenin O-β-D-glucopyranosyl-(1→2)-β-D-galactopyranoside. The biose which forms the sugar moiety of timosaponin A-III was obtained as crystals from the partial hydrolyzate of the saponin and named timobiose.
