Biological features of Hedysarum alpinum L. cell culture when grown in vitro

The purpose of the research conducted was to obtain a cell culture of Hedysarum alpicum, as a producer of xanthone mangiferin, by achieving the tasks of obtaining a cell culture of H. alpium growing in deep-cultivation conditions and studying its physiological characteristics.

Material and methods. The object of the study was a cell culture of H. alpine obtained from the cotyledon of the germination, strain H. alpinum (C) 2016 of the collection of FSBSI «All-Russian Scientific Research Institute of Medicinal and Aromatic Plants» and the native plant grown on the pharmacopeial site of the Botanical Garden of FSBSI «All-Russian Scientific Research Institute of Medicinal and Aromatic Plants», harvest of 2013.

Results. It has been established that growth regulators kinetin and 2.4D stimulate growth processes of H. alpium (C) cell culture 2016 in deep cultivation conditions. The duration of growth is 20–23 days. The maximum increase corresponds to 16 g/l on the 20^th day of growth. The maximum consumption of oxygen by the cell culture is 30·10^-4 mol/l·h on the 16^th day of growth, when the cells are in the regular growth phase.

Conclusion. As a result of the work carried out, a stable cell strain of H. alpium was obtained, growing on the surface of the agarized nutrient medium, which has the potential for the synthesis of mangiferin and work has been carried out on studying its physiological characteristics.
