| DPPH Free Radical Scavenging Capacity A |
| Product Name: DPPH Free Radical Scavenging Capacity Assay Kit Test method: Colormetric Size: 120T/ 50S
Product Description
DPPH free radical is a very stable nitrogen-centered free radical. It is one of the important indicators of the
sample's antioxidant capacity and is widely used in the research of antioxidant foods, health products and
pharmaceuticals.
The DPPH radical has a single electron, and its alcohol solution is purple, with strong absorption at 515 nm.
When an antioxidant present, DPPH free radicals are cleared, the solution color becomes lighter, and the
absorbance at 515 nm decreases. Within a certain range, the change in absorbance is directly proportional to
the degree of free radical removal. In this kit, the ability of the sample to remove DPPH free radicals is
reflected by the degree of decrease in absorbance.
