Biological activity of the iridoid glycosides extract from Linaria genistifolia (L.) Mill. has been investigated, namely its infl uence on the resistance of the winter wheat Odesschi 51 plant to the caused by the Fusarium oxysporum and Helminthosporium avenae pathogenic fungi root rot. Our results indicate that summary iridoid glycosides from this plant, containing four major known compounds: 5-O-allosylantirrinoside, antirrinoside, linarioside and 6-β-hidroxiantirride, can be successfully employed in biological control of the afore-mentioned wheat pathogens: it stimulates wheat grains germination and embryonic root growth in conditions of fungal infection. 1H and 13C NMR characteristics of 5-O-allosylantirrinoside in Py-d5 are for the fi rst time presented. Structures of two conformers of 5-O-allosylantirrinoside in D2O and Py-d5 solutions are proposed, based on the experimental NMR evidence and molecular modelling studies. |
