Synthesis of Silver Nanoparticles Using Reactive Water–Ethanol Extracts from Murraya paniculata

Abstract

Using the radiation–chemical simulation method of free radical reactions with 2,2-diphenyl-1-picrylhydrazyl, we were able to show high antiradical activity of water–ethanol extracts from Murraya paniculata. This will allow for the creation of new bioactive antioxidants based on them. The formation of silver nanoparticles (Ag-NP) was determined using the silver-ion reduction process by M. paniculata extracts. A band of electronic plasmon resonance was identified in the optical absorption spectra of hydrosols of Ag-NP using extracts of dried M. paniculata leaves. A decrease in the number of Candida albicans and Pseudomonas aeruginosa cells after introduction into the Ag-NP system synthesized by the reduction of silver cations using M. paniculata extracts indicates their moderate antimicrobial activity.

Emerging Trends in the Application of Green Synthesized Biocompatible ZnO Nanoparticles for Translational Paradigm in Cancer Therapy

“…The use of plant-based substrates eliminates exposure to hazardous microorganisms and the accompanying health risks and safety concerns. Obtaining plant extracts for this purpose is a straightforward process that involves exposing the plant to a solvent, such as distilled water or ethanol [56,57]. Various parts of the plant, such as leaves, roots, seeds, and fruits, have been utilized for the synthesis of zinc oxide nanoparticles [58,59].…”

The influence of medicine plant extracts on viability of yeast cells of Saccharomyces cerevisiae and Saccharomyces carlsbergensis under the action of ionizing radiation

“…Control of the quantity and quality of stress and antistress factors, selective enhancement or suppression of their action on microbial cells can be used to obtain positive effects in the systems of synthesis and destruction of substances, control of growth and physiological activity of microorganisms with simultaneous, conjugate flow of microbiological, chemical and photochemical processes; taking into account the possibility of pro-oxidant and antioxidant effects of the components of the nutrient medium on the cells of microorganisms. Substances with oxidant and pro-oxidant activities can be formed directly during the cultivation of microorganisms during chemical and photochemical processes, while some of them may exhibit both pro-oxidant and antioxidant properties; combating phenomena such as blooming of reservoirs, the effects of toxic substances of algae and plants during photosensitization on biota and humans; improvement of biological purification methods using IOP Publishing doi:10.1088/1755-1315/1061/1/012051 2 microorganisms, microalgae and plants; the use of biologically active substances [4][5][6][7][8] and additives based on microorganisms and plants for feed, veterinary, food and medical prophylactic purposes, for post-radiation therapy.…”
