Indian journal of pharmaceutical education and researchSummary: Background: Plant elements such as carbohydrates, lipids, flavonoids, polyphenols,
enzymes, terpenoids, and alkaloids are used as reducing substance in the green
production of silver nanoparticles. The strategy proved to be highly straightforward,
cost-effective, and practical. Materials and Methods: The synthesis of nanoparticles was
validated using optical inspection, in which the yellow colour solution became brown.
UV-visible spectroscopy, XRD, FTIR analysis, and SEM were used to further characterise
the material. Results: Transmission electron microscopy have shown that the silver
nanoparticles size was between 10–46 nm (SEM). Size of silver nanoparticles was
found to be between 10–46nm approximately as determined by transmission electron
microscopy (SEM). Well diffusion method demonstrated the antifungal activity of AgNPs
on
Magnaporthe oryzae with the zone of inhibition of 5 and 11mm when 12.5 and 25μg/
ml of AgNPs was used respectively. Lowest inhibitory concentration was found to be
5.2. Conclusion: The leakage of reducing sugars and proteins was used to explore the
mode of action of nanoparticles’ antifungal activity, indicating that AgNPs were able to
reduce membrane permeability.
