Analysis of Brazilian Plant Extracts as Potential - Antiox
In this work, 22 alcoholic extracts, obtained from 14 species of plants belonging to four families, used for different food and medicinal purposes in Brazil, were evaluated for their capacity to inhibit the reduction of the free radical, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and to protect Saccharomyces cerevisiae cells, an eukaryotic cell model...

Evaluation of Antioxidant Activity and Inhibition of
picrylhydrazyl (DPPH) at 6.5 x 10-5 M and 0.1 mL of methanol solutions of plant extracts (1000 ppm) or positive control (quercetin) were mixed and the absorbance of the reaction was read at 515 nm. The test was performed in triplicate at various concentrations of the plant extracts in mg/mL[8].
