Significance of DPPH free radical
DPPH free radical is a stable organic radical widely utilized in laboratory assays to evaluate the antioxidant activity of various substances. It is essential for determining the scavenging potential of natural antioxidants by measuring their ability to reduce DPPH, indicated by a color change from violet to yellow. This evaluation method is commonly used for various compounds, including herbal formulations and plant extracts, to assess their effectiveness in scavenging free radicals, which highlights their antioxidant capacity.
