Capsicum annuum Fruit Extract: A Novel Reducing Agent for the Green Synthesis of ZnO Nanoparticles and Their Multifunctional Applications

Abstract

A simple, efficient and convenient method for the preparation of zinc oxide (ZnO) nanoparticle was described. Several parameters like size and morphology of the prepared nanoparticles were characterized thorough a variety of analytical techniques such as XRD, FT-IR, UV-Vis, SEM, and EDX. The prepared ZnO nanoparticles were successfully used as catalyst for the formylation of amino acid esters and biodiesel synthesis. Further, the synthesized formamide esters were well characterized through HRMS, 1H NMR and 13C NMR analysis and subjected for the in vitro antibacterial and antifungal tests and the results indicated that some of them showed promising activity against targeted bacterial pathogens.

Green Synthesis of Gold and Silver Nanoparticles Using Leaf Extract of Capsicum chinense Plant

“…Extracts obtained from different species of the genus Capsicum ( C. annuum , C. frutescens , C. baccatum and C. chinense ) were shown to be a good option for the green synthesis of nanoparticles [ 15 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. However, few studies have used extracts from a plant organ other than the fruit, such as leaves [ 26 , 27 ].…”

Seaweed Mediated Fabrication of Zinc Oxide Nanoparticles and their Antibacterial, Antifungal and Anticancer Applications

“…[12] The bioactive compounds act as a capping agent, which eventually improves biogenic nanoparticles' shelf life and stability. [13] Numerous biological resources had been used for the synthesis of ZnO NPs, such as Mangifera indica leaves, [14] Capsicum annuum fruit, [15] Tabernaemontana divaricata leaf, [16] Nyctanthes arbor-tristis flower [17] and ocean-based seaweeds and microorganisms. [18.19] Seaweeds are one of the richest reservoirs of compounds with structural diversity and multiple activities [20] and have efficiently assisted the formation of NPs for biomedical applications.…”

Bryophyllum pinnatum mediated synthesis of zinc oxide nanoparticles: characterization and application as biocontrol agents for multi-drug-resistant uropathogens

“…Diffuse reflectance spectroscopy was carried out on LAMBDA 750 (PerkinElmer) UV-Vis NIR Spectrophotometer. A wavelength range of 300–800 nm was used to record the spectra using diffuse reflectance mode, eventually, converted into absorbance coefficient by applying Kubelka–Munk function [ 29 ]. The band gap value was examined from the plot of Kubelka–Munk function versus the energy of the absorbed light.…”
