Biogenic synthesis of zinc oxide nanoparticles using root extract of <em>Anacyclus pyrethrum</em>

Abstract

Introduction: Nanoparticle synthesis can be carried out via various physical, chemical, and biogenic methods. Nanoparticles are easily synthesized with the help of bacteria and plant extracts. Utilizing root extract in the biogenic synthesis of nanoparticles is a non-toxic and environmentally beneficial method.

Objective: The present study is aimed to synthesize zinc oxide (ZnO) nanoparticles using an eco-friendly biological approach. The study also aims to explore and compare the antioxidant potential of the synthesized ZnO nanoparticles with that of the Anacyclus pyrethrum root extract.

Methods: This method makes use of aqueous extract from Anacyclus pyrethrum roots. The phytochemical analysis of the root extract has been analyzed using qualitative methods and the antioxidant potential has been determined using DPPH analysis. The ZnO nanoparticles have been characterized using spectrophotochemical analysis.

Results: The aqueous extract was found to contain significant phytochemicals that act as a significant reducing agent that aid in stabilization of the synthesized nanoparticles. The synthesized ZnO nanoparticles exhibited absorbance at 362 nm. The root extract was found to possess significant antioxidant potential owing to the presence of polyhydroxy phytochemicals

Conclusions: The antioxidant potential of the biosynthesized ZnO nanoparticles was significantly higher than that of the root extract. Thus, the root extract of A. pyrethrum as well the biogenic ZnO nanoparticles can be explored for pharmaceutical benefits.
