Significance of DPPH radical scavenging activity

DPPH radical scavenging activity is a method used to assess the antioxidant capacity of various substances by measuring their ability to neutralize DPPH free radicals. This assay evaluates how effectively antioxidants can donate hydrogen or electrons to the stable DPPH radical, leading to a color change that indicates antioxidant strength. Various extracts, including those from plants like Nigella sativa and Moringa Oleifera, are analyzed using this method to showcase their potential antioxidant effectiveness.
