The aim of this work was to establish antioxidants biochemical profile of Alchornea cordifolia vitro-plants, grown on substrate with different manganese concentrations, for the suitable use of regenerating in a phytoremediation program of soils polluted by this element. Conductivity and pH including essential parameters in assimilation of minerals by the plant were studied on substrate cultures. There was no significant difference in these two parameters on the four substrates tested, with an average of 4.7 and 188.63 μS/cm, respectively for pH and conductivity. Guaicol peroxidase (GOPX) activity was higher in leaves and stems, on media with high concentrations of Manganese (Mn) residues. In substrates containing low concentration of Mn, this activity was more important on roots. As for Glutathione (GSH), its activity was also greater on the leaves with a maximum value of 2.356 nmol/g on the substrates.
