The metals contents of plants are variable, due to the factors like differences between the plants species, geographical area, conditions of drying process. Metals contents in soil are a great importance for their effect of animals and humans, through the biologic chain: soil – plant – feed and food. Analysis of metals content was made with ContrAA-300, Analytik-Jena device, by flame atomic absorption spectrometry (FASS) in air/acetylene flame. It were analyzed the macro elements content for 33 medicinal plants. The main macro elements (Ca, Mg K and Na) were quantified for each sample. The contents in macroelements for analysed samples were in range: 3.763 % (Plantago major) – 0.442 % (Hippophae rhamnoides), for Ca; 0.718% (Urtica dioica) – 0.107% (Hippophae rhamnoides and Pinus), for Mg; 1.417% (Chelidonium majus) – 0.319% (Rhamnus frangula), for K and 1.945% (Cynara scolymus) – 0.021% (Pinus), for Na.
