Determination of selected toxic elements in leaves of White Hawthorn grown in a remote area

Abstract

Abstract.One important plant of the Rosaceae family which is commonly used as phytopharmaceutical in Europe and North America is Hawthorn (Crataegus monogyna). The fruits, the leaves together with their extracts are applied in patients suffering mild cardiac disorders or nervosity. Since the leaves as well as the berries act as diuretics a sufficient micronutrient supply has to be guaranteed. On the other the quantities of toxic elements present in the plant parts should be at levels without harmful effects on human health. For this purpose Hawthorn leaves and flowers were collected in a remote area in 2011 and 2012 and analysed for their elemental composition. The metals uptaken from the soil were supposed to be in a similar range, thus the impact of airborne contamination by heavy metal translocation could be studied. The elements investigated were Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, and Zn. After harvesting the samples were dried, homogenized, digested and then analysed by ICP-AES. The contents of all elements are in the µg/g range. In the samples of 2012 higher concentrations were found for Co, Cu, Mn, Ni, and Zn, lower concentrations were registered for Ba, Pb, and Sr. The amounts of Cd and Cr were statistically insignificantly lower in 2012 than 2011.

Determination and Analysis of Trace Elements in Five Kinds of Traditional Chinese Medicine in High Blood Pressure Medicinal Food by ICP-AES

“…For Zn, Mn, and Cu, their concentrations in the present study were higher in red dates (16.50 μg/g, 11.5 μg/g, and 6.70 μg/g), wolfberry (52.30 μg/g, e Zn (17.55 μg/g) and Cu (9.35 μg/g) contents in yam were higher in comparison with the published data by Cônsolo and Zhuang et al [18,19], while the Fe (42.65 μg/g) content was lower in comparison with the published data by Shin and Cônsolo et al [18,20]. In wolfberry, the Zn (52.30 μg/g) and Mn (12.95 μg/g) contents found in the present work were close to the levels found in the literature by Zeiner (13.80-21.10 μg/g, 9.21-11.27 μg/g) [21]. e Fe (109.65 μg/g) concentration was much higher and the Mg (842.00 μg/g) concentration was much lower than those in the literature.…”

“…e Cr (3.75 μg/g) and Co (6.70 μg/g) contents of red dates and hawthorn were much higher than those in the literature (0.11-0.17 μg/g and 0.02-0.16 μg/g) [15,21]. In coix seeds, the Fe (42.65 μg/g), Mn (32.30 μg/g), and Ca (178.90 μg/g) contents were close to the levels given in the literature [16], while the Pb (7.48 μg/g) concentration was higher and the Cd concentration was lower than those given in the literature by Cônsolo and Zhang [16,18].…”

Influence of Soil Salinity on Selected Element Contents in Different Brassica Species

“…The levels of the elements detected are in a range comparable to that given in the literature [ 20 , 21 , 22 , 23 , 24 ]. When using literature data, it is crucial to check how the data are presented, i.e., whether they refer to fresh mass or dried matter and to which mass (100 g or 1 kg) [ 22 , 24 ], or if they list the mass of a certain element considering the entire plant [ 19 ]; it is also necessary to check which growing conditions and climatic influences are considered [ 13 , 15 ]. Furthermore, the pollution background of the soil where the vegetables grow determines the elemental contents observed in the plants and needs to be considered when comparing data, such as in the Ethiopian study with sampling carried out in an industrial area [ 23 ] or in another study analysing an area with high impact of atmospheric deposition [ 25 ].…”

“…One important aspect is the metal load in the surroundings, i.e., the soil composition as well as the pollution of the respective site [ 13 , 14 ]. Each site is also characterized by its climatic conditions, whose changes can even influence the uptake in the same plants across different years [ 15 ]. Species-specific metal uptake and accumulation can be studied by analysing various plants grown in the same area in order to exclude other influencing parameters.…”

Comparative Characteristics of the Influence of Technology of Extraction on Antioxi-Dant Properties for the Farry and Flowers of the Tender (Crataegus)

“…Более низкие концентрации зарегистрированы для Ba, Pb и Sr. Объем токсических элементов Cd и Cr статистически незначительно ниже в 2012 г. по сравнению с 2011 г. [7]. В статье ученых [8] объектом исследования были листья и цветы с дикорастущих растений боярышника (11 различных генотипов) из провинции Ирана, собранные в 2014 году.…”
