Two new steroidal glucosides,26-O-β-D-glucopyranosyl (25S)-furost-5-ene-1β,3β,22α,26-tetraol 1-O-β-D-xylopyranosyl-(1→3)-[α-L-rhamnopyranosyl-(1→2)]-β-D-fucopyranoside and (25R) spirost-5-ene-3β,14α-diol-3-β-O-β-L-rhamnopyranosyl-(1→2)-[β-D-xylopyranosyl(1→4)]-β-D-glucopyranoside,were isolated from the Ophiopogon japonicus (L.f.) Ker-Gaw.Their structures were elucidated by spectroscopic methods.
