The content of biologically active compounds in various species of the genus Arnica L. in the conditions of introduction in the territory of the Arctic zone of the Russian Federation (Kola Peninsula)

Phenolic compounds are widespread secondary metabolites capable of absorbing reactive oxygen species, regulating the activity of various enzymes, cell cycles, DNA and protein functions, lipid peroxidation and possessing proven pharmaceutical significance for humans. Representatives of the genus Arnica (Arnica L.) – Arnica Chamisso (Arnica chamissonis Less.), lanceolate arnica (Arnica lanceolata Nutt.), double arnica (Arnica sororia Greene), soft arnica (Arnica mollis Hook.), long-leaved arnica (Arnica longifolia D.C.Eaton), perennial herbaceous boreal species growing on territories of North America and Europe with antioxidant, antitumor and anti-inflammatory properties. Due to the need to search for species containing significant concentrations of phenolic compounds for cultivation and use as medicinal raw materials, a comparative analysis of the content of phenolic compounds in extracts of inflorescences of representatives of the genus Arnica L. cultivated under conditions of introduction in the Arctic zone of the Russian Federation was carried out. Based on the conducted research, it is possible to characterize the soft arnica (Arnica mollis Hook.) as a species that is a potential source of phenolic compounds with high pharmaceutical significance, and recommend it for introduction into culture in order to obtain plant material with a high content of biologically active compounds.
