Green Synthesis of Silver Nanoparticles from Rotheca serrata (L.) Steane & Mabb., its Physicochemical Characterization and Evaluation of its Biological Activities

Abstract

Background of the topic: In recent years, nanoparticle synthesis is an area that is extensively used in various scientific fields. Green synthesis of the silver nanoparticle is much more cost-effective. Purpose of the study: This work is based on the study of the synthesis of silver nanoparticles (AgNPs) by using the leaf extract of Rotheca serrata (L.) Steane & Mabb belongs to the family Verbenaceae. The study also involves the characterization of AgNPs and their antibacterial, antioxidant, anti-inflammatory activity and effect on germination. Method: Rotheca serrata was collected from Nilambur, Kerala. Consequently, the biosynthesis of silver nanoparticles was carried out with aqueous extract, and characterization was done by using the UV-Vis spectra, at the frequency of 200 - 600 nm by the spectrometer, XRD, and FTIR and checked the biological activities. Result: The green synthesized AgNPs from Rotheca serrata showed significant antimicrobial, antioxidant, and anti-inflammatory properties and also showed excellent effects on the germination of four species of common vegetables. Through this method, we examined the plant response to AgNPs in the pure culture technique. Conclusion: Rotheca serrata-based AgNPs can be used for the production of nano products and this will definitely. The synthesis of nanoparticles by using Verbenaceae is an eco-friendly, reliable process while also being suitable for large-scale production. Furthermore, it is a prompt and easy-to-handle process when compared to the chemical, physical, and microbe-mediated synthesis processes.
