Abstract
The elemental composition of the roots of Siberian sea-buckthorn ( Hippophae rhamnoides L. ssp. mongolica Rousi) grown under the endemic conditions of West Siberia was studied in detail by synchrotron radiation X-ray fluorescence (SR-XRF) analysis. The joint quantitative content of K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Pb in roots and soil was determined, as well as biological adsorption coefficients of these elements from soil. Peculiarities of adsorption of elements, specific for this biological genus, were determined. In comparison with aboveground organs (leaves, bark and fruits), Siberian sea buckthorn roots are characterized by the maximum adsorption of vitally necessary chromium, iron, molybdenum and selenium. Additionally, extremely high adsorptions of elements with unidentified biological role were detected: niobium, zirconium, titan and yttrium. The effect of over-concentration with roots was determined for niobium and molybdenum. Due to a high accumulation level of chromium, Siberian sea-buckthorn roots can serve as perspective sources of biogenic flora of this vitally necessary element for preventive care purposes to fight so called civilization diseases - diabetes and atherosclerosis. It was shown that Siberian sea buckthorn roots in the amount of 1.5-2.0 g ensure the daily need of the organism in chromium. It was concluded that sea buckthorn was not a concentrator of lead recognized as a toxic element, since its uptake by roots is comparable to the average index for plants in the earth's land surface.
