Significance of DPPH method
The DPPH method is an important experimental technique used to evaluate the antioxidant activity of various substances by measuring their ability to scavenge the DPPH free radical. This method involves assessing how effectively compounds can reduce DPPH radicals, which are stable free radicals, leading to measurable changes such as a color shift in the solution. Widely utilized in laboratories, the DPPH method serves as a reliable assay for determining the antioxidant potential of different extracts and compounds.
