Two new bisdesmosidic spirostanol saponins were isolated from the underground parts of Ruscus aculeatus. Their structures were determined to be (23S)-spirosta-5,25(27)-diene 1β, 3β, 23-triol 1-O-{O-β-D-glucopyranosyl-(1→3)-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl} 23-O-β-D-glucopyranoside and (23S)-spirosta-5,25(27)-diene-1β, 3β, 23-triol 1-O-{O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl} 23-O-β-D-glucopyranoside on the basis of spectroscopic analysis, including two-dimensional NMR techniques, and the result of hydrolysis.
