Determination of the Macro Elements Content of Some Medicinal Herbs

Abstract

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.
