This work deals with the elemental analysis of different elderberry (Sambucus nigra L.) cultivars. In the theoretical part the botanical characteristics of elderberry, including its extension and places of occurrence, the possibilities of collecting the various parts of the elderberry and its use in food and cosmetics is described. A large part is devoted to the occurrence and characteristics of minerals in food, and to the methods that are suitable for elemental analysis and decomposition of biological material. The aim of the experimental part was to analyze different cultivars of elderberry and juice made from this cultivars, and to determine concentration of selected elements (Zn, Mn, Fe, Mg, Cu, P, Ca, Na and K) using ICP–OES. The total amount of 24 cultivars was analysed from which 6 varieties were harvested in two different seasons in 2011 and 2013. Measured concentrations of elements in different varieties of elderberry were mutually compared using statistical methods. The differences between the content of elements in fruits and juice, obtained by pressing the fruit, and the effect of seasonal conditions on the content of elements in the fruit juice from different elderberry cultivars were studied.
