In vitro bioaccessibility of metals sourced of tape tea: low cost drugs

Resumo

An in vitro bioaccessibility of metals was considered in this study to evaluate the toxicity of tape tea, a low cost drug. Taking into account total element determination, Co, Ni, Mn, Fe and Zn were found at higher concentrations, compared to other metals, and, then, their bioaccessibility was evaluated, employing the UBM protocol. According to our results, Mn, Ni, Zn and Co are fully presented in the bioaccessible fraction, whereas Fe was observed only 50% bioaccessible.
