Members of Asteraceae family have properties enabling their application for medical purposes. The major- and microelement content in 15 medicinal species of the Asteraceae family growing in the National Botanical Garden, Republic of Moldova was determined by instrumental neutron activation analysis. A total of 31 chemical elements, Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Mo, Sb, Cs, Ba, La, Ce, Sm, Tb, Hf, Ta, Th and U, were identified in herbal samples. Potassium was found to be the most abundant major element: its content in plants ranged from 20,700 mg/kg in Artemisia lerchiana to 58,000 mg/kg in Matricaria recutita. The content of other major elements existed in the following ranges: Ca from 4700 to 14,200 mg/kg and Mg from 1710 to 3870 mg/kg. The maximum content of Mg, K and Ca in analyzed plants was higher compared to data presented in the literature. Among essential microelements the most abundant were Fe (83&ndash:910 mg/kg), Mn (23&ndash:150 mg/kg) and Zn (27&ndash:76 mg/kg). The daily intake of metal and the health risk index for selected elements (As, Ni, Sb, V, Mn, Cr, Co, U, Sr, Al, Fe, and Zn) were calculated. Health risk indexes were obtained for V and Co in Calendula officinalis, Tanacetum balsamita, Achillea clypeolata, Artemisia balchanorum, Artemisia lerchiana, Helichrysum arenarium, and Matricaria recutita. The principal component analysis showed three associations of elements, which can be defined as physiological, geological and anthropogenic sources of elements.
