AVALIACAO DA COMPOSICAO MINERAL DO CHA DA FOLHA SENESCENTE DE Montrichardia linifera (Arruda) Schott (Araceae) POR ESPECTROMETRIA DE ABSORCAO ATOMICA COM CHAMA (FAAS)

摘要

Levels of Ca, Mg, Fe, Zn, Cu and Mn were determinated by FAAS in the tea and dry matter from senescent leaf from Montrichardia linifera, plant used in folk medicine Amazon. The content of these metals that are transferred of the leaf to the infusions have presented significant reductions, however, the Mn values in the infusion may exceed the tolerable daily intake (11 mg) if consumption of this tea is greater than 1.0 L per day. So the tea of senescent leaves of M. linifera may be considered as a toxic beverage and thus its use is not advised.
