Estimation The Scavenging Activities of Ascorbic Acid, Uric Acid, Gallic Acid and GSH to DPPH Radical
Keywords:DPPH, scavenging activity, antioxidants, Ascorbic Acid, Uric Acid, Gallic Acid
The “?,?-diphenyl-?-picrylhydrazyl radical (DPPH)” method from the estimation methods to determine
the antioxidants activity in vitro, through the lowering the absorbance of DPPH with color changing from
violet into yellow with increasing the strength of antioxidants activity. So, the results of this study show the
uric acid is the strongest scavenging, then ascorbic acid when compared with other compounds used. But the
reduced glutathione is the weakest although has acidic hydrogen.
