| Background | 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. |
| Biological Activity | DPPH是一种稳定的自由基，可用于测量抗氧化剂的自由基清除活性。DPPH 中氮原子的奇数电子通过从抗氧化剂吸收氢原子而还原为相应的肼。DPPH 方法可用于水性和非极性有机溶剂中，并可用于检查亲水性和亲脂性抗氧化剂[1]。 |
