ХАУТТЮЙНИЯ (HOUTTUYNIA CORDATA THUNB.) – НОВАЯ ДЛЯ РОССИИ ОВОЩНАЯ И ЛЕКАРСТВЕННАЯ КУЛЬТУРА (МОРФОЛОГИЧЕСКИЕ ОСОБЕННОСТИ И БИОХИМИЧЕСКИЙ СОСТАВ)

Taking into account the importance of Hauttuynia cordata as a vegetable and medicinal plant in the South-East Asia, and the possibility of its cultivation in a temperate climate, the morphological and biochemical features of the plants belonging to ‘common’ and ‘variegated’ forms were studied in conditions of a greenhouse. We used a peat as a sub-strate for growing plants. The content of macroand microelements in rhizomes and leaves was estimated with use of the synchrotron radiation induced X-ray fluorescence analysis (SR-XRF). During three months of cultivation, the total phytomass of ‘common form’ increased from 4.7 ± 0.84 g to 30.3 ± 8.00 g, i.е. in 6.4 times, while in rhizomes it reached 51-56% out of the total phytomass. The size of the leaves of ‘variegated form’ was 15 29% less, as com-pared with the ‘usual form’. The height of the plants was 25.9 ± 0.98 cm in the ‘usual’ and 29.0 ± 0.62 cm in the ‘variegated’ form, the length and width of the leaf blade were 6.6 ± 0.26 x 5.9 ± 0.25 and 4.70 ± 5.00 x 4.90 ± 5.50 cm, respectively. Plants of the ‘common’ form formed api-cal, elongated, dense, ctenopod spine inflorescence with flowers lacking perianth, with three stamens and 3-4 fused carpal forms forming syncarpous gynoecium. ‘Variegated’ form did not form any inflorescences. H.cordata leaves con-tain 35, 6 mg% ascorbic acid, rhizomes ‒ 14.2 mg%. Leaves of H.cordata mainly accumulated Mn, Fe and Cu, and the roots ‒ Fe, Co, Cu and Zn. It is necessary to carry out the further study on new promising functional food.Учитывая важное значение, придаваемое хауттюйнии Hauttuynia cordata Thunb. в качестве овощного и лекарственного растения в странах юго-восточной Азии, а также возможности его выращивания в условиях умеренного климата, исследовали в условиях теплицы ФБГНУ ЦСБС СО РАН, г. Новосибирск (54°49′33″ с. ш. 83°06′34″ в. д.) морфологические и биохимические признаки растений двух форм (обычной и вариегатной) вида. В качестве субстрата использовали верховой торф. Содержание в корневищах и листьях макрои микроэлементов определяли методом РФА-СИ. За три месяца выращивания фитомасса растений обычной формы уве-личилась с 4,7±0,84 г до 30,3±8,00 г, т.е. в 6,4 раза, при этом на долю корневищ приходилось 51-56% от общей фитомас-сы. Размер листьев вариегатной формы оказался на 15-29% меньше, по сравнению с обычной формой. Высота растений была 25,9±0,98 см у обычной и 29,0±0,62 см – у вариегатной формы; длина и ширина листа, соответственно, 6,6±0,26 х 5,9±0,25 и 4,70±0,19 х 4,90±0,17 см. Растения обычной формы формировали верхушечное, продолговатое, плотное, початковидно-колосовидное соцветие с цветками, лишенными околоцветника, с тремя тычинками и 3-4 сросшимися плодолистиками,              образующими синкарпный     гинецей. Вариегатная форма соцветий не образовывала. В листьях H.cordata накапливается 35,6 мг/% аскорбиновой кислоты, в корневищах – 14,2 мг/%. В наибольшей степени листья H.cordata концентрируют Mn, Fe и Cu, а корни – Fe, Co, Cu и Zn. Необходимо дальнейшее изучение этого растения и c целью позиционирования его в качестве перспективного функционального продукта питания

HOUTTUYNIA (HOUTTUYNIA CORDATA THUNB.) – NEW VEGETABLE AND MEDICINAL CROP FOR RUSSIA (MORPHOLOGICAL FEATURES AND BIOCHEMICAL COMPOSITION)

Chemical elements in the mineralization of plant residues under soil pollution with heavy metals

Mineralization processes of plant residues in background and anthropogenically affected areas are analyzed. The multielement composition of plant residues before and after their exposure in soil is provided with the help of synchrotron radiation (XPA SR). It is demonstrated that the destruction process is accompanied by changes in the chemical composition of plant residues. Chemical elements with concentrations increasing as they are filtrated from soil into the exposed samples are determined. Agrobotanical groups of plants with the highest infiltration rate are revealed. © 2013 Pleiades Publishing, Ltd. Russian Academy of Sciences, RAS Ministry of Education and Science of the Russian Federation, Minobrnauka: 1.1.08, 5.5329.2011Development Program of Lead ing Science Schools (NSh 5325.2012.4)Programs of the Presidium of the Russian Academy of Sciences, Ural Branch (project no. 12 I 4 2051)Russian Foundation for Basic Research (project no. 10 04 00146 a)

Chemistry for Sustainable Development 18 (2010) 4959 Elemental Blood and Hair Composition of the Russian North Native Inhabitants with Different Biogeochemical Environment

Abstract Elemental composition has been studied for the blood of Chukchi people living in the continental part of Chukotka, and Eskimo people living at the coast of the Bering Bay, as well as for a group of Novosibirsk townspeople. Elemental composition has been determined for the hair of the Chukchi and Yakut people living in the continent. Using the Synchrotron Radiation X-ray Fluorescence An alysis (SR XFA) technique, a simultaneous determin ation of chemical elements in the blood of the mentioned populations has been performed, as it follows: K, Ca, Fe, Cu, Zn, Ge, Se, Br, Rb, Sr, Zr, Pb. The technique potentialities of determining the concentration of chemical elements in the hair of some groups of Yakut and Chukchi men and women using XPA SR have allowed detecting simultaneously K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Mo, Hg, Pb, Bi. Individual, sexual and region al differences in the concentration of elements in blood and hair of the populations under investigation have been established. The data obtained have allowed us to estimate the level of elemental exchange for some groups of Chukchi, Yakut, Eskimo people, to reveal the features of elemental distribution, as well as to perform a certain biogeochemical characterization of the environment

ASSOCIATION OF MINERAL ELEMENTS IN THE ATHEROSCLEROTIC PLAQUE IN CORONARY ATHEROSCLEROSIS

Purpose: to determine the content of mineral elements in the homogenates of atherosclerotic plaques of human coronary arteries. Methods: research material – homogenates of samples of atherosclerotic plaques of coronary arteries obtained during coronary bypass surgery. The concentration of chemical elements Ca, Pb, Fe, Cu, Zn, Br, Sr, Zr in the homogenates of atherosclerotic plaques was determined by x-ray fluorescence analysis using synchrotron radiation (SRXRF). Results: in all the studied samples the predominant presence of Ca was observed, in stable plaques 1791.93±3042.25 µg/ ml, in unstable atherosclerotic plaques 2024.33±1267.13 µg/ml.Association of Ca with Fe (r = 0.798; p < 0.01), Zn (r = 0.963; p < 0.01) and Sr (r = 0.981; p < 0.01) in the atherosclerotic focus was revealed. No significant difference between the measured elements in stable and unstable plaques was found. Conclusion: the method x-ray fluorescence analysis using synchrotron radiation revealed some patterns of the mineral composition of an atherosclerotic plaque of a human. The main mineral component of the atherosclerotic plaque is calcium, with a tendency to increase the concentration of the element in the unstable focus. Minor components-iron, zinc, strontium are associated with calcium. In this case, iron tends to reduce the concentration in an unstable atherosclerotic focus, and the concentration of strontium and zinc does not change significantly

Measurements of Physicochemical Characteristics of Atmospheric Aerosol at Research Station Ice Base Cape Baranov in 2018

We discuss the results of measurements in the region of Cape Baranov (the Severnaya Zemlya archipelago) of the set of physicochemical characteristics of atmospheric aerosol: aerosol optical depth, aerosol and black carbon concentrations, elemental and ion compositions of aerosol, organic and elemental carbon contents in aerosol, as well as the isotopic composition of carbon in the aerosol and snow samples. It is shown that the average values of most aerosol characteristics, measured in April–June 2018, are a little lower than in the Arctic settlement Barentsburg (Spitsbergen archipelago) and several-fold smaller than in the south of Western Siberia in the same period
