Abstract

Humanity makes use of medicinal plants for prevention and treatment of various diseases since antiquity until the present time, approximately, 80% of the population still uses this medical resource as one of the first types of unconventional treatment for health care. The Amazon population has a habit of using various medicinal plants, so this study aims to determine the concentration Ca, Fe, Mg, Mn and Zn in five medicinal plants and their teas, sold in the market Ver-o-Peso, in the city of Belem-PA. The plants were studied: Carqueja (Baccharis trimera), chapéu de couro (Echinodorus grandiflorus), confrei (Symphytum officinale L.), erva doce (Pimpinela anisum) and losna (Artemisia absinthium L.). The samples were digested in a microwave oven and subsequently analyzed by flame atomic absorption spectrometry (FAAS). Results showed that in teas, plants that have the highest levels of elements were losna for Ca and Zn (3668.40 e17.03 mg kg-1, respectively), chapéu de couro for Fe and Mn (282.38 and 156.64 mg kg-1, respectively) and erva doce for Mg with 2108.50 mg kg-1. Elemental analysis of medicinal plants serves as a complementary data regarding its nutritional assessment, therefore, in this study it was possible to the plants analyzed no risk of toxicity when ingested their teas.
