Assessment and Evaluation of DPPH Radical Scavenging Activity of 2-(Furan-2′-yl)-3-hydroxy-4Hchromen-4-one and Their Derivatives

The 2-(furan-2'-yl)-3-hydroxy-4H-chromen-4-one and their substituted derivatives have been synthesised with electron donating and electron withdrawing classes. The activity of free radical scavenging was studied using 22'-diphenyl-1-picrylhydrazine (DPPH). The effect of these groups on percentage scavenging behaviour is explained by kinetic
