The determination of elemental composition is important information since it can lead to potential toxic effects and product stability. In this work, we developed and validated a method using inductively coupled plasma mass spectrometry (ICP-MS) to determine both major and minor elemental constituents of urucum seeds with excellent figures of merit. Essential elements such as Ca, Mg, and K are present in percentage levels, whereas Al, Ba, Co, Cu, Fe, Mn, Mo, Ni, and Zn are in the mg kg−1 range, and Cd, Cr, Pb, and Se are found in µg kg−1 concentration. Statistical tools such as hierarchical grouping and PCA showed that elements such as Cr and Fe, Mn and Ni, and Cu and Zn are intrinsically correlated, and Mo was present heterogeneously throughout the samples, indicating that soil preparation and treatment can be a potential cause to this dispersion. The elemental composition of urucum seeds and its statistical interpretation is also presented to aid future studies with nutritional composition and farming procedures.
