Three phenolic glycosides 5-O-{[5''-O-E-(4'''-O-threo-guaiacylglycerol)-feruloyl]-beta-apiofuranosyl-(1-->2)-beta-xylopyranosyl} gentisic acid, 5-O-[(5''-O-vanilloyl)-beta-apiofuranosyl-(1-->2)-beta-xylopyranosyl] gentisic acid and 1-O-[E-(4'''-O-threo-guaiacylglycerol)-feruloyl]-3-O-beta-galacturonopyranosyl glycerol were isolated and identified from the roots of Medicago truncatula together with four known 5-O-beta-xylopyranosyl gentisic acid, vicenin-2, hovetrichoside C and pterosupin identified for the first time in this species. Structural elucidation was carried out on the basis of UV, mass, (1)H and (13)C NMR spectral data.
