Abstract	A steadily growing culture of genetically transformed roots of a valuable medicinal Altaic plant Hedysarum theinum Krasnob. was established using a Ri-plasmid (pRi) T-DNA of A4 wild strain of Agrobacterium rhizogenes. The composition of secondary substances accumulated in the in vitro roots and the roots of H. theinum intact seedlings was investigated. Isoflavonoids were found to represent by their main low-molecular metabolites. Preparative HPLC made it possible to isolate four substances from the methanolic extract of H. theinum cultured roots. Using $^{1}$H- and $^{13}$C-NMR-spectrometry, these substances were identified as formononetin, ononin (formononetin glycoside), malonyl ononin, and texasin glucoside. The qualitative composition of secondary metabolites of the genetically transformed roots and the roots of H. theinum seedlings was essentially the same, except that malonyl ononin was not found in the latter. The technique of producing artificial seeds on the basis of H. theinum roots cultured in vitro was tested, and the possibility of their use as a rhizogenic inoculum was substantiated. The culture of H. theinum roots is considered as a potential source of ecologically pure raw material for medicinal preparations, and the artificial seeds with root inoculum are a promising vehicle for propagation and conservation of this valuable plant.
