Two new steroidal saponins, diuranthosides D and E, were isolated from the whole plant of Diuranthera inarticulata Wang et K. Y. Lang. By means of spectral and chemical analysis, the structure of the new compounds were established as neotigogenin-3-O-(-D-glucopyranosyl (1?3)-(-D-xylopyranosyl-(1?3)-[(-D-glucopyranosyl(1?2)]-(-D-glucopyranosyl(1?4)-(-D-galactopyranoside (1) and neotigogenin-3-O-(-D-glucopyranosyl(1?3)-(-D-glucopyranosyl (1?3)-(-D-xylopyranosyl(1?3)-[(-D-glucopyranosyl(1?2)]-(-D-glucopyranosyl(1?4)-(-D-galactopyranoside (2) respectively.

Two novel 27-norergostanol steroids, panthogenins A （1） and B （2）, possessing unusual rings E and F featuring a ketal moiety at C-25 were isolated from rhizomes ofDioscorea panthaica. Their structures and relative configurations were elucidated by extensive spectroscopic methods including 1D and 2D NMR techniques, and the structure of panthogenin A was further confirmed by X-ray crystallography. Both compounds showed potent in vitro insulin sensitizing activity.
