Phytochemical analysis revealed that the infusion of Rumex dentatus is rich in flavonoids, phenolics, reducing sugars and total sugars. The plant infusion found to possess a significant antioxidant activity. The aqueous extract of Rumex dentatus has been used as a green reducing and stabilizing agent in addition to its desirable biological activity. The biosynthesis of reduced silver nanoparticles was very fast, and silver nanoparticles were synthesized by exposure of a mixture of different ratios of 4 mM AgNO3 and Rumex dentatus aqueous extract to UV-irradiation at room temperature. Ultraviolet-visible absorption spectroscopy, transmission electron microscopy and X-ray diffraction confirmed reduction of Ag+ ions and formation of silver nanoparticles. Varied morphology of the bioreduced silver
nanoparticles was recorded. On contrast to the main plant infusion, the resulting sil.. View More»
