Antioxidant Activity of Abies webbiana Mediated Zinc Oxide Nanoparticles

Background: Biological methods for nanoparticle (NP) synthesis using microorganisms, enzymes, and plants or plant extracts have been suggested as possible eco-friendly alternatives to chemical and physical methods. Aim: The aim of the current study is to synthesize Zinc oxide nanoparticles (ZnO NPs) mediated by Abies webbiana and to evaluate its antioxidant activity.  Materials and Methods: Bio-mediated synthesis of metal oxide nanoparticles using A. webbiana is a promising alternative to traditional chemical synthesis. The antioxidant activity of zinc oxide (ZnO) NPs was synthesised using DPPH radical scavenging assay. Results: The ZnO NPs were  identified by  dark brown  color  and  the  surface  plasmon resonance  was  positioned at a peak  at  290  nm. Finally, the current study has clearly demonstrated that the ZnO NPs are responsible for significant high antioxidant activities. Conclusion: Therefore, the study reveals an efficient, eco-friendly, and simple method for the green synthesis of ZnO NPs using a green synthetic approach.
