Abstract

Maslačak (lat. Taraxacum officinale) je biljka iz porodice Asteraceae poznata po svojim ljekovitim svojstvima te se dugi niz godina uspješno koristi širom svijeta u prehrambenoj industriji kao potpuno netoksična i jestiva biljka. Maslačak je bogat izvor fenolnih kiselina (cikorinska kiselina), flavonoida (derivati luteolina), terpena (seskviterpenski laktoni), vitamina (A, C, K...) i elemenata (kalcij, natrij, magnezij, željezo, bakar). Zagađenje tla i biljaka potencijalno teškim elementima (PTE) poput Cd, Co, Cr, Cu, Fe, Mn, Ni, Zn i drugih, postaje predmet znanstvenih istraživanja zbog njihove štetnosti za ljudsko zdravlje. Koncentracija potencijalno teških elemenata koja predstavlja prijetnju okolišu na površini tla uzrokovana je kemijskim sastavom izvornih stijena i antropogenih aktivnosti, kao i sposobnosti sorpcije tla. Prije mjerenja metodom ICP-MS provela se priprava uzoraka djelovanjem smjese dušične kiseline i vodikovog peroksida u uređaju za mikrovalno potpomognutu razgradnju. Određen je različit sadržaj makro- i mikroelemenata u različitim dijelovima biljke maslačka.

Abstract (english)

Dandelion (lat. Taraxacum officinale) is a plant from the Asteraceae family. It is renowned for its medicinal properties and is widely utilized in the food industry as a completely non-toxic and edible plant. Dandelion is a rich source of phenolic acids, flavonoids, terpenes, vitamins (A, C, K, etc.), and elements (calcium, sodium, magnesium, iron, copper). Soil and plant contamination with potentially toxic elements (PTE) such as Cd, Co, Cr, Cu, Fe, Mn, Ni, Zn, and others have become a subject of scientific research due to their harmful effects on human health. The concentration of potentially toxic elements posing environmental risks in surface soils is influenced by the chemical composition of anthropogenic activities and the soil's adsorption capacity. Before measuring using the ICP-MS method, sample preparation was carried out by treating the samples with a mixture of nitric acid and hydrogen peroxide in a microwave-assisted digestion device. The different content of macro- and microelements was determined in different parts of the dandelion plant.
