Abstract
The objective of this work was to verify the antioxidant effect of the flav onoid compounds quercetin, naringenin, morin, and rutin isolated from soybe an, cultivar UFV-5. After acetylation with acetic anydride and pyridine, an d methylation with diazomethane, indexes of acidity, iodine, and peroxide a nd Kreiss reaction were determined. The best results were obtained with met hylated naringenin, acetylated naringenin, methylated quercetin, and acetyl ated quercetin.
