摘要

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.
