In the present study, we report an eco-friendly way for the synthesis of silver nano particles using the medicinal plant Arevalanata, which is belongs to a family of Amaranthaceous, we synthesise silver nano particles by utilizing the reduction property of Arevalanata stem extract ,at room temperature. UV-Visible absorption spectroscopy was used to monitor the quantative formation of silver nano particles. Characterization of these particles was done by using Fourier transform infrared spectroscopy (FTIR),scanning electron microscopy (SEM),transmission electron microscopy (TEM) and X-ray diffraction method(XRD). These silver nano particles show strong antibacterial activity towards against E.coli, Staphylococcus aureus, Bascilluscereus and Pseudomonas aeruginosa
