Antioxidant and free radical scavenging effects in extracts of the Achyrocline alata (Kunth) DC. in comparison with the extracts of the Achyrocline satureioides (LAM.) DC.

Achyrocline alata (Kunth.) DC. and Achyrocline satureioides (Lam.) DC. are species belonging to the family Asteraceae widely used in the folk medicine of Campo Grande, Mato Grosso do Sul, being considered substitute plants. The present work aimed to compare the obtained extracts of these species to simple chemical assays, in order to test the antioxidant activity and free radical scavenging, using β-carotene and DPPH as reference, respectively. With these assays it was observed that the obtained extracts of Achyrocline satureioides were more active, as free radical scavenging, than the same obtained extracts of Achyrocline alata. These chemical assays were compared to a known patterned, quercetin, and and they were dealt under triplicate basis.
