Abstract
The elemental structure of green leaves of Siberian sea buckthorn (Hippophae rhamnoides L. ssp. mongolica Rousi) growing under endemic conditions of the West Siberia was studied. The simultaneous quantitative content of K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rd, Sr, Y, Zr, Nb, Mo, Pb in green leaves and soil, as well as coefficients of biological absorption of these elements were determined by the method of RFA-SR (X-ray fluorescence analysis using synchrotron radiation). Species-specific absorption features of elements by leaves of sea buckthorn were revealed, what was expressed in the increased accumulation of vitally necessary chrome and elements with unidentified biological role: niobium, scandium, titan, zirconium and strontium, relatively to the terrestrial phytomass. It was shown that leaves of Siberian sea buckthorn could serve a food source of vitally necessary chromium and manganese in the form of the easily digestible biogenic form. It was established that fruits of sea buckthorn do not concentrate toxic chemical elements: lead and arsenic.
