Rumax dentatus Synthesis of Silver Nanoparticles, Antimicrobial Activity and Characterization

AgNPs (Silver Nanoparticles) are frequently used in medicine due to their potent antimicrobial activity and AgNPs effectively produced by a variety of physico-chemical and photochemical reduction. Polygonaceae family comprises 200 species; Rumax dentatus are one of them present worldwide, used as food, exhibiting flavors, taste, and aroma and mild laxative properties, and utilized as medicine for a long time. In our current study, the chemical synthesis of silver nanoparticles (AgNPs) using the extract of plant species Rumax dentatus was reported. Extraction was performed through the soxhlet method. Additionally, the nanoparticles were screened against gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacterial strains. The chemical-synthesized NPs (Nanoparticles) were characterized using UV-Visible spectroscopy, XRD (X-ray diffraction) and SEM (scanning electron microscopy) for structural morphology average size and confirmation of AgNPs. The shift of yellow to brown -red color indicated by the extract showed the chemical synthesis of AgNPs. The greater antimicrobial activity was found against Escherichia coli and closed to standard control. XRD and SEM morphological analysis showed morphological characteristics showed agglomerated polydispersed spherical shape of nanoparticles as and indicated high displayed inconsistent morphology which caused by aggregation or agglomeration of nanoparticles and is accountable of Rumax dentatus plant extract.
