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 studies and the co-relation of excited state intramolecular proton transfer (ESIPT) with the electron donating…
