Significance of DPPH photometric assay
The DPPH photometric assay is a widely utilized method for evaluating the free radical scavenging ability of antioxidants. It employs DPPH, a stable free radical, to measure the scavenging capacity of antioxidant compounds in various samples, including leaves and fish. By assessing the decrease in absorbance of the DPPH solution, the assay effectively determines the antioxidant capacity based on its ability to inhibit the DPPH radical, making it a valuable tool in antioxidant research.
