ABSTRACT. The chemical composition of all plants is represented by components of both organic and mineral origin. The mineral complex affects the human body, includes various macroelements, trace elements, ultramicroelements, as well as toxic compounds. Polemonium caeruleum L. has long been approved for medical use, however, to date there is no data giving a complete picture of the mineral composition of the plant.
The purpose of the study is to investigate the elemental composition of the plant material of blue cornelian fern, cultivated in the Voronezh region.
Materials and methods. The objects of the work were dried samples of the grass of Polemonium caeruleum L. of the first and second years of vegetation, and a sample of rhizomata cum radicibus of Polemonium caeruleum L. of the second year of vegetation, prepared according to the rules of collection from cultivated plants in the city of Bobrov, Voronezh region. The mineral composition of the studied objects was studied by the method of chromatography-mass spectroscopy with inductively coupled plasma.
Results. The analysis of elements of the grass and rhizomata cum radicibus of Polemonium caeruleum L. cultivated in the Voronezh region was carried out. The elements in the grass of Polemonium caeruleum L., regardless of the year of collection, are distributed as follows (in descending concentration): macroelements K˃Ca˃P˃Mg˃Na, in underground organs Ca˃K˃P˃Mg˃Na; trace elements in the grass of blue polemonium Si˃Al˃Fe˃Sr˃Mn˃Zn, in underground organs Si˃Al˃Fe˃Ti˃Mn˃Zn˃Sr. Elements of strong accumulation in the grass of Polemonium caeruleum L. are P, K, Ca, Hg. In rhizomata cum radicibus, elements of strong accumulation include P, Zn, Sr. Toxic elements in the plant material of bluehead are at an acceptable level, however, with further cultivation of the plant it is necessary to take into account the fact of their ability to accumulate and capture by the plant.
Conclusions. The plant material of Polemonium caeruleum L. is a promising source of elements (in particular potassium, silicon, etc.) and can be recommended for diseases associated with their deficiency. The content of 58 elements was determined by the chromatograph mass spectrometry method. Differences in the accumulation of elements depending on the morphological part of the plant, but also the year of vegetation were established.
