Abstract :
Naringenin (NaR) is a flavonoid, mostly found in citrus fruit. Its IUPACname is 5,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one. Naringenin is lipophilic in nature and possessing antioxidantproperty. In present study,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one was incorporatedonto CuO nanoparticles (CuO-NPs) for enhancing its antioxidant activity. The CuO-NPs and itsfunctionalized form (CuO-NaR) were characterized byFourier-transform infrared (FT-IR)spectroscopy,X-ray diffraction (XRD),Scanning electron microscope(SEM) andEnergydispersive X-ray (EDX) analysis. The CuO-NPs, CuO-NaR and NaR were examined fortheircomparative antioxidant activities followed by DPPH (2,2-Diphenyl-1-picrylhydrazyl) method.The results revealed that the antioxidant activity of CuO-NaR was enhanced significantly.
