The content of saicosaponins and flavonols in different organs of the aerial part of the golden snail (Bupleurum aureum Fisch. ex Hoffm.) upon introduction in the Komi Republic

The results of an introductory study of Bupleurum aureum in the collection of medicinal plants of the Botanical Garden of the Institute of Biology of the Komi Science Center of the Ural Branch of the Russian Academy of Sciences are presented. It has been revealed that plants of this species are characterized by high winter hardiness and resistance in culture. For 102–110 days of vegetation, they go through all phases of development and form full-fledged seeds. As a result of the research, the morphological features of the generative shoot have been studied. Under the conditions of culture, the golden boletus is able to form 2–6 (7) generative shoots per individual with a height of 109–137 cm. The distribution of saicosaponins and flavonols in the aerial organs of the golden voles has been studied using the methods of differential spectrophotometry and chromato-mass spectrometry. The highest rates of biologically active substances in the phase of mass flowering have been found in the leaves and inflorescences of the golden lily, the lowest – in the stems. It has been found that the concentration of biologically active substances in the stem leaves depends on the position of the leaves on the shoot. The mass fraction of saikosaponins in the leaves has increased from bottom to top along the shoot from 1,66 to 3,07%, flavonols – from 1,75 to 4,5%. The maximum amount of flavonols have been found in inflorescences – complex umbrellas (6,23%). The obtained analytical data allow us to state that the above-ground phytomass (leaf, inflorescence) of cultivated plants of golden boletus is characterized by high levels of saikosaponins and flavonols and can be recommended for use as a medicinal plant material.
