Resumo: | The extraction of copper, manganese and zinc by different organic solvents and aqueous solutions from powdered and droughts of nine medicinal plants were investigated as a possible way of accomplishing the speciation of these metals in such samples. The extractants were 75 g L-1 HCl, 50 g L-1 NaCl, 50 g L-1 NaOH, 50g L-1 Na2CO3, (1: 1) glicero-alkali solution, pure water, ethanol and ether. None of the organic solvents extracted significant amounts of the three elements. For Cu, only the HCl solution has shown significant extraction efficiency. On average, Zn was more efficiently extracted when H2O, NaOH, and Na2CO3 solutions were used while Mn was more efficiently extracted with the HCl and NaCl solutions. The differentiated extraction behavior of the studied elements in relation to the different aqueous extractants is an indicative of different pools of these elements in the plant substrate. |
