A study has been first made of the element composition of both the plants of six species from three families, growing in the Mountain Altai and the soil samples from their habitat by method of X-ray fluorescence analysis using synchrotron radiation (SRXRF) at the station of element analysis of SCSTR of the Institute of Nuclear Physics SB RAS (VEPP-3 store ring). The material studied was represented by the plants of six species of three families, collected in July of 2017 in the South-East and Central Altai. Potentilla fruticosa and Sibiraea altaiensis of the Rosaceae family, Myricaria longifolia of the Tamaricaceae family. The plants Caragana of the Fabaceae family are represented by three species - Caragana bungei, Caragana pygmaea and Caragana pygmaea subsp. altaica. We have analyzed the leaves and stems of bushes and soil samples of four habitats of the plants studied. Reliable data were obtained on the content of 20 elements in plant and soil samples. A comparative analysis of soil samples from the different habitats of the Mountain Altai indicate that the content of most of the elements varies steadily within a narrow range (ν ≤ 2,5), calculated as ν = Cmax/Cmin. The greatest variability was recorded only for Br, As (ν > 5) and Mo (2,5 ≤ ν ≤ 5). The highest total content of K and Ca is revealed in the leaves and stems of the representatives of Caragana and in the leaves of S. altaiensis. The high total content of microelements was found in C. pygmaea and C. pygmaea subsp. altaica. Considerable differences were recorded in the accumulation of elements in the aerial organs of the bushes studied. In the leaves, the content of Mn varies within a very narrow range (ν ≤ 1,5); that of Pb varies within a narrow range (ν=2,3); the content of Cr, As, Ca, Zn, Cu and K varies, on the average, in the mean range (2,5 ≤ ν ≤ 5), the content of the rest elements varies within a large range. In stems, the concentration of Cu varies within a short range (ν=1,8), Mn, Zn, Pb and K – within the average one, the others – within a wide range. The high content of Ca, Fe, Sr, Mn, Zn, Ti, Zr, Mo and Co is determined in the leaves and stems of the plants Caragana, mainly C. pygmaea subsp. altaica; the high content of Y, Rb, Br, Cu, Cr and Ni is found in the leaves of M. longifolia, K – the leaves of S. altaiensis. Thus, it has been established that the highest accumulation of macro- and microelements is typical of the representatives of Caragana of the Fabaceae family, the low content is typical of the plants Potentilla and Sibiraea of the. Rosaceae family. The content of most of the chemical elements in aerial organs of the representatives of various taxons varies at high level. The data obtained on the content of 20 elements are reliable and may be included in databases.
