Macro and trace element accumulation by species of genus Artemisia on the southern coast of the Crimea
Element composition of herbs is an important quality parameter indicating degree of herbs' safety and impact of mineral content on its biological activity. The genus Artemisia L. (wormwood) includes more than 400 species that are widely used in traditional medicine, nutrition and as a medicinal raw material in pharmaceutical industry. The main attention of researchers is attracted by the amount and chemical composition of Artemisia essential oil, as well as antioxidant activity indicators. Using inductively coupled plasma-mass spectrometry (ICP-MS) accumulation of 26 elements by seven Artemisia species: A. abrotanum L., A. annua L., A. dranculucus L., A. feddei Levl. &. Vant., A. santonica L., A. taurica Willd. and A. scoparia W.K., grown in an ecologically friendly area (the Nikita Botanical Gardens, the southern coast of the Crimea), was investigated for the first time. A. dranculucus and A. abrotanum demonstrated the highest content of minerals, while the lowest levels were typical for A. taurica. Among the studied species, new natural Se accumulator was identified: A. dracunculus cultivar 'Izumrud', containing up to 23 mg Se kg‑1 d.w. with the coefficient of biological accumulation value reaching 88. A. scoparia was shown to accumulate elevated levels of heavy metals (Al, As, Cr, Pb and V). A. annua plants were characterized by maximum levels of copper, manganese, iodine and zinc. Great variations in sodium content allowed to indicate A. santonica as species with the highest sodium concentration (1.525 mg kg‑1 d.w.), and A. feddei - with the lowest one (47 mg kg‑1 d.w.). The results may be important in view of solving problem of human selenium deficiency via A. dracunculus 'Izumrud' utilization, quality evaluation of edible Artemisia species and in investigations of physiological peculiarities of plant tolerance to soil salinization.
