| Background | DPPH radical is a very stable nitrogen-centered free radical and is one of the important indicators of sample antioxidant capacity.It is widely used in the research of antioxidant foods, health supplements, and pharmaceuticals. CheKine™ Mirco DPPH Free Radical Scavenging Capacity Assay Kit provides a simple, convenient, and rapid method for measuring DPPH radical scavenging activity, suitable for plant tissues, red wine, and other liquid samples.The principle is based on the fact that DPPH radicals possess an unpaired electron, giving their ethanol solution a purple color with strong absorption at 515 nm. In the presence of antioxidants, DPPH radicals are scavenged, causing the solution color to fade and the absorbance at 515 nm to decrease. Within a certain range, the change in absorbance is proportional to the degree of radical scavenging. |
