e., a dpph radical scavenging activity purple hue. An FRS antioxidant, such as, reacts to DPPH to form DPPHH, which has a decrease absorbance than DPPH due to lower number of hydrogen. It's radical compared to the DPPH-H form, because it results in decolorization, or a yellow hue, as the number of electrons absorbed improves. Decolorization influences the lowering capability significantly. The moment the DPPH solutions are coupled with the hydrogen atom resource, the reduce state of diphenylpicrylhydrazine is formed, shedding its violet colour.
