Objective To study water-soluble constituents of Dioscorea zingiberensis in order to seek active components. Methods Various chromatographic techniques were used to isolate the constituents. Structures of compounds were elucidated by spectroscopic analyses of 1H-NMR, 13C-NMR, 135DEPT, HMQC, HMBC, and TOCSY. Results One new steroidal saponin was isolated and identified as 26-O-(?-D-glucopyranosyl)-(25R)-furost-5-en-3?, 26-diol-22-OMe-3-O-{?-L-rhamnopyranosyl-(1→4)-[?-D-glucopyranosl-(1→3)-?-D-glucopyranosl-(1→2)]-?-D-glucopyranoside}.
