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.
