Stinging nettle (Urtica dioica L.) is a perennial plant belonging to the Urticaceae family. Several studies have reported the presence of the different classes of chemical compounds, which expressed a beneficial effect on human health. Among them there are elements and minerals that are essential for the proper functioning of organism. Mineral occurrence requires analytical data about the content. For such purposes was developed and validated a method based on the optical emission spectroscopy coupled with inductively coupled plasma (ICP-OES). Minerals and elements were extracted using two conventional methods (Soxhlet and maceration) and two non-conventional (ultrasound- and microwave-assisted techniques). The extracts were analyzed resulting in high diversity in the composition. Non-conventional techniques showed better results, since those extracts possessed high content of the macroelements and iron as well, instead the toxic elements were found in trace amount View Full-Text
