The study of the elemental composition of Camelina sativa (L.) Crantz and Camelina microcarpa Andrz.

Abstract

The aim of the research was to conduct a comparative study of the qualitative composition and quantitative content of macro- and microelements in the seeds of the Camelina sativa ( L .) Crantz and Camelina microcarpa Andrz . Materials and methods. Seeds of the Slavutych Camelina sativa ( L .) Crantz and Camelina microcarpa Andrz . were selected as the subject of the study. Samples of seeds were provided by the National Center for Plant Genetic Resources of Ukraine. The seeds were collected in summer 2017 on the territory of Zaporizhzhia and Poltava region. To determine the qualitative composition and quantitative content of macro- and microelements, an atomic emission spectrograph method with photographic registration on the DFS-8 device was used. Results. The obtained experimental data on the macro- and microelement composition of the seeds of Camelina sativa ( L .) Crantz and Camelina microcarpa Andrz . indicate that there are at least 19 elements in the raw material. The seeds of Camelina sativa ( L .) Crantz accumulate in the largest quantities (mg/100 g): 1) macroelements: potassium – 1500, phosphorus – 470, magnesium – 235, calcium – 190; 2) microelements: ferrous – 16,4, zinc – 7,0, aluminum – 3,0, manganese – 2,8, nicole – 1,78, cuprum – 1,12. The accumulation of elements in the Camelina microcarpa Andrz. differs from their content in the seed of the Camelina sativa ( L .) Crantz and amounts to (mg/100 g): 1) macroelements: potassium – 840, magnesium – 105, calcium – 105, phosphorus – 85; 2) microelements: ferrum – 2.7, zinc – 2.5, aluminum – 2.3, manganese – 1.5. Conclusions . As a result of atomic emission spectrography with photographic registration, elemental composition has been established in the seeds of the C. sativa ( L .) Crantz and C. microcarpa Andrz for the first time. 19 elements have been detected. In the seeds of the Camelina sativa ( L .) Crantz , the content of each of the elements prevails over the content of the elements in the Camelina microcarpa Andrz seeds. The obtained results testify the prospect of further phytochemical study of biologically active substances of vegetative raw materials of the Camelina sativa ( L .) Crantz and Camelina microcarpa Andrz. , in order to find new medicinal plants and to create new drugs based on them.
