摘要: Arrabidaea chica (Humb. & Bompl.) Verl. is an herb popularly used in the treatment of anemia Brazilian Amazon region, and little known about its mineral content. Therefore, elemental contents Cu, Fe, Mn, Zn were determined dried leaves tea obtained by decoction infusion three varieties medicinal plant using flame atomic absorption spectrometry after acid wet digestion samples. In general, levels minerals are good agreement with other studies involving plants, variety AC2 had highest concentrations all elements both tea. Iron was found to be most abundant (38.4–115.5 µg g−1), whereas manganese extraction efficiencies (56.1–62.7%) (45.6–63.6%). Additionally, more efficient almost elements. The consumption may contribute a small proportion daily requirements Mn.
