DPPH is a stable free radical that can be used to measure the free radical scavenging activity of antioxidants. The DPPH radical has a single electron, its alcohol solution is purple, and has a strong absorption at 517nm. When free radical scavenger is present, its absorption gradually disappears due to its single electron pairing, and its degree of fading is quantitatively related to the number of electrons it accepts, so it can be used for rapid quantitative analysis by spectrophotometer.
