The present study aimed to evaluate the content of mineral elements of leaves, ethanolic extract and a tea infusion leaf of Anacardium occidentale L., known as cashew, has economic importance and is used for the treatment of diseases by the population. Thus the mineral study shows become of interest as far agricultural as medicinal. Methods: All the elements were determined using Flame Atomic Absorption Spectrometry (FAAS). The samples were divided into two groups according to the leaves used: young and adult. Result: Determination of elements showed that the higher concentration of Ca (73.74±0.47 mg/L), Mg (57.45±8.04 mg/L), and Fe (22.75±0.36 mg/L) occurred in the mature ones. In the young, the highest concentrations observed were Ca (12.08±0.11 mg/L), Mg (35.24±0.13 mg/L), and Fe (10.65±0.72 mg/L). Zn showed no significant difference and the Cu concentration was higher in young leaves. During the infusion, no significant differences were observed between adult and young, where Mg was the compound with the highest concentration (4.35±0,07 mg/L and 4.35±0,01 mg/L for mature and young leaves, respectively). In the extract, the element with higher concentration was Ca (74,85±1,26 mg/L), followed by Mg (30.75± 1.5mg/L) and Fe (21.28±1.62mg/L).
