Evaluation of Level of Essential Elements and Toxic Metal in the Medicinal Plant Hymenaea martiana Hayne (Jatobá)‎ Used by Mid-West Population of Brazil

Abstract EN

Hymenaea martiana Hayne belongs to the family Fabaceae (Leguminosae) and presents the popular name of jatobá.

It is a tree that demonstrates medicinal purposes and represents a food source in Brazil.

The potential contribution of each species to recommended nutrient intakes (DRI) and Brazilian Health Surveillance Agency (ANVISA) for children and adults were calculated.

A comparison between the quantified contents of micro- and macronutrients Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S, and Zn in leaves tea and tea of the bark of this plant was made with the recommendation of FDA and ANVISA.

General safety regarding metal content (Na, K, Ca, Fe, Zn, and Ni) and nonmetal (P) was assured as none of them exceed the safety limit of the daily intake.

However, the content of Mn observed in the teas of H.

martiana Hayne is above the UL for tolerable intake level for children aged 1-6 years.

There are no limits established for the UL of Cr and S for children and adults.

The data on quantification of mineral concentration in the species Hymenaea martiana Hayne obtained can serve as a tool to decide the dosage of preparations from this plant used for medicinal purposes.
