Two new steroidal saponins were isolated from the rhizome of the Chinese native plant, Speirantha gardenii (Hook.) Baill. Their structures were established as 22-methoxy-(25R)-5β-furostane-1β,3β,4β,5β,26-pentaol 26-O-β-D-glucopyranoside (I) and 22-methoxy-(25R)-5β-furostane-1β,2β,3β,4β,5β,26-hexaol 26-O-β-D-glucopyranoside (II) on the basis of chemical and spectral evidences.
