experimental part, p. 438 - 441 (2011/02/23)
The absolute stereochemistry of blumenol C glucoside and byzantionoside B was revised here as (6R,9S)- and (6R,9R)-9-hydroxymegastigman-4-en-3-one 9-O-β-D-glucopyranosides, respectively, by modified Mosher's method. The empirical rules of 13C-NMR chemical shift to determine the absolute stereochemistry of C-9 of 9-hydroxymegastigmane 9-O-β-D-glucopyranoside were also discussed.

Five megastigmane glycosides have been isolated from the seeds of Trifolium alexandrinum L., of which two are known compounds, while three are new compounds showing the presence of apiofuranosyl-(1→2)-glucopyranosyl residue as a sugar moiety. The structures of the isolated compounds were established on the basis of NMR and mass spectral data.
