Description
Summary:The purpose of this paper was to evaluate the concentration of some essential microelements (Fe, Mn, Zn and Cu) from the leaves of two plants: stinging nettle (Urtica dioica) and sage (Salvia officinalis), species of plants with multiple uses in the food and medical field due to their high content of compounds with beneficial action for organisms. Samples were obtained by washing, drying and calcination of fresh leaves. The results obtained by atomic absorption spectrometry regarding Mn, Fe, Zn and Cu concentration in sage and nettle leaves shows that the samples contains important amounts of essential microelements, Cu (1.72-1.87 mg/g), Fe (25.43-65.67 mg/g), Mn (7.86 – 9.30 mg/g), Zn (54.61 – 73.12 mg/g). The appreciable contents of essential microelements recommend the use of these plants as a supplementary source of essential elements.
