The decrease of DPPH, a steady free radical, is Employed in the DPPH Evaluation system. The DPPH free radical interacts with the odd electron to generate an absorption highest wavelength of 517 nm (purple shade). Antioxidants combine with DPPH and Merge the existence of the hydrogen resource (for instance, a free-radical scavenging antioxidant), leading to the reduction of DPPH to DPPHH and a reduction in DPPH absorbency.
