Significance of DPPH
DPPH, or 1,1-diphenyl-2-picrylhydrazyl, is a stable free radical widely used in scientific research as a standard reagent for assessing the antioxidant activity of various substances. It is instrumental in free radical scavenging assays, where a decrease in its absorption indicates antioxidant activity. By measuring the radical scavenging ability of antioxidants, DPPH plays a crucial role in determining the efficacy of plant extracts and other compounds in combating oxidative stress.
