THE SMART TRICK OF DPPH SCAVENGING ACTIVITY THAT NO ONE IS DISCUSSING

DPPH is often a properly-recognized radical plus a trap ("scavenger") for other radicals. Hence, fee reduction of the chemical reaction upon addition of DPPH is used being an indicator on the radical nature of that reaction. Because of a powerful absorption band centered at about 520 nm, the DPPH radical has a deep violet colour in solution, and i
