Antioxidant activity of gold nanoparticles synthesized using Lemna minor

Abstract

The production of nanoparticles under nontoxic, green conditions is of vital importance to address the growing concerns on the overall toxicity of metallic nanoparticles for medical and technological applications. The present findings disclose Lemna minor synthesized gold nanoparticles antioxidant property. The free radical scavenging activity of the synthesized nanoparticles was determined by DPPH assay, Superoxide radical scavenging, Nitric oxide radical scavenging and Hydrogen Peroxide scavenging. The radical scavenging activity obtained in this study with Lemna minor synthesized by gold nanoparticles shows significant scavenging activity and as good antioxidant property. The antioxidant activity of natural compounds reported to be mainly due to redox properties in absorbing and neutralizing free radicals, quenching singlet and triplet oxygen or decomposing peroxides.
