Summary: | Heavy metals, chemical elements considered toxic at certain concentrations, can be considered potential threats to plants, animals, and biological resources of a particular ecosystem. Among them, mercury and aluminum, when involved in bioaccumulation processes, can cause damage to various organ systems of both animals and plants. In vegetables, heavy metals produce reactive oxygen species (ROS), which are involved in the occurrence of malformations and deficits in the growth of roodets and plumule of several species of plants, which justifies the study of natural antioxidant agents that may come to reverse or ameliorate the deleterious effects caused by these compounds. In this sense, this study aims to evaluate the cytoprotective effect of hydroethanolic extract of
Stryphnodendron rotundifolium
Mart., species popularly known as “barbatimão” against the heavy metals mercury and aluminum in vegetable model, because of its known antioxidant potential. To this end, there was the cytoprotection test in microbial and lettuce seeds (germination) in order to ascertain the potential of the said extract on the protection of roots and stem this. It was observed that the extract showed no allelopathic effect on lettuce seeds at a concentration of 32 μg/mL and in combination with HgCl
2
and AlCl
3
, it enabled a higher growth in the roodets and stem
Lactuta sativa
L. These results demonstrated that the extract of
Stryphnodendron rotundifolium
can be an alternative to solve the problem with soil contamination by heavy metals, showing thus its promising potential cytoprotective in plant species. |
