Journal Article
Phyto-Synthesis and Characterization of Parthenium-Mediated Iron Oxide Nanoparticles and an Evaluation of Their Antifungal and Antioxidant Activities and Effect on Seed Germination
2023
Overview
The present research provides a safe method for synthesizing iron oxide nanoparticles using leaf extract of
Parthenium hysterophorus
. The novelty of the present study is the utilization of
P. hysterophorus
biomass as a reducing, capping, and stabilizing agent for the production of iron oxide nanoparticles with antifungal and antioxidant potential. The size, shape, crystalline nature, stability, functional groups, and purity of as-synthesized nanoparticles were analysed. Spherically shaped, with an average size of 17.5 nm, highly stable and crystalline
Parthenium
-mediated iron oxide nanoparticles were produced. In addition, the antifungal activity was screened against fungal pathogens (
Aspergillus niger
and
A. flavus
) using well diffusion method. The growth of both funguses was inhibited by iron oxide nanoparticles. The antioxidant activity was performed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. A higher concentration of iron oxide nanoparticles showed higher free radical scavenging activity compared to ascorbic acid. The IC
50
value was 184.3 µg/ml. The seed germination assay was performed using
Sesamum indicum
and
Arachis hypogaea.
A lower concentration of
Parthenium
-mediated iron oxide nanoparticles, rather than higher ones, triggered the germination level.
Parthenium
-mediated iron oxide nanoparticles may be used as nano-fungicide in biomedical and agricultural fields to improve human health and agriculture productivity.
