Abstract:

In the present research silver nanoparticles was produced by naturally reduction of silver ions from plant extracts by using silver nitrate as a precursor and investigate the effects of phytochemical, ascorbic acid and total phenolic content on reduction of silver ions from plant materials.  In the presence of ascorbic acid concentration 38.88µg/gm and 35.5088µg/gm and the phenolic contents concentration 97.89µg/gm and 26.99µg/gm in Chenopodium and Marigold extracts respectively the multiple plasmon peaks were observed at the range of 360-426nm with absorbance of 0.780-0.925cm-1  in chenopodium extract with absorbance 0.392-0.569 cm-1 in marigold extract.  The appearance of multiple surface plasmon peaks indicated the spherical shape of silver nanoparticles. Obtained multiple plasmon resonances at 360-426nm and 310-450nm in Chenopodium and Marigold extracts, respectively may be indication of maximum reduction of Ag+ ions and this enhancement of maximum reduction of Ag+ ions due to the presence of ascorbic acid and total phenolic content higher concentrations.


Keywords: Silver nanoparticles; ascorbic acid; phenolic contents; chenopodium extract; marigold extract
