Antidiabetic activity of silver nanoparticles from green synthesis using Lonicera japonica leaf extract

Abstract

In this work we report the green synthesis of silver nanoparticles (AgNPs) using the aqueous leaf extract of Lonicera japonica.

“…9b). The strong DPPH and ABTS radical scavenging potential of AgNPs may be due to their ability to donate electrons or hydrogen ions as well as the capping agents (phytochemicals) on the surface of AgNPs, and its smaller size (Gurunathan et al 2013;Thatoi et al 2016;Balan et al 2016).…”

“…In vitro free radical scavenging activity of Ag nanoparticles DPPH scavenging effect of the AgNPs solution was determined according to the procedure reported earlier (Balan et al 2016). In this assay, about 2 mL of DPPH (1,1-diphenyl-2-picrylhydrazyl) solution was mixed in 0.2 mL of various concentrations of the AgNPs solution and then the reaction mixture was vortexed and kept at room temperature for 30 min in the dark.…”

“…These reactive species overwhelm antioxidative defenses of the host organism, which contributes to diverse pathologies, such as inflammatory diseases, tissue injury, accelerated cell death, cardiovascular and neurodegenerative diseases, and development of cancer (Ajitha et al 2014;Mata et al 2015). Although AgNPs display considerable antioxidant activity in vitro, their clinical significance has not yet been ascertained (Mata et al 2015;Balan et al 2016). Moreover, the rapid acceleration of resistance against commercial antimicrobial agents has provided opportunities to explore new drug developments for untreatable infections.…”

“…The antibacterial potential of AgNPs are due to the clemency of Ag + ions from nanoparticles. [16][17][18] The bactericidal activity of AgNPs depends not only on their size but also on the pH, salt concentration and the medium in which it is diffused. 19 Nano-silver's unique physical and chemical properties make it highly bioactive such that it can react with cells, microorganisms and macro-organisms.…”

“…Both the synthesized copolymers (PEOSEB and PEDDAD) reacted with four to five colonies of Mueller Hinton Agar (MHA) medium, incubated at 37°C for 12 hours. The culture suspension turbidity was noted with a sterile saline solution, such that the final bacterial inoculum would contain 5×10 5 CFU/mL 19,20 . Using a sterile glass spreader the test organism were vaccinated on a well of 6 mm (dia) nutrient agar plates and disseminated uniformly with a sterile cork borer.…”
