Abstract: Rhododenderon campanulatum is a decumbent shrub of Ericaceae family. In India, it is distributed (in alpine region from 3000m-3640m asl) in Jammu and Kashmir, Uttarakhand and Himachal Pradesh. It is commonly known as white burans. Phytochemical screening of methanolic and aqueous extract of R. Campanulatum reveals the presence of glycosides, flavonoids, tannin, saponin in, etc. It is toxic in nature. The present study deals with the green synthesis of silver nanoparticles. In green synthesis of Ag-NPs, the silver nitrate solution and the aqueous plant extract were mixed well in the different ratios.The metal ion present in the solution reduced as Ag+1 to Ag0 within three days. In the spectrophotometric observation the λmax peak of Ag-NPs of R. campanulatum flowers (RCF) obtained at 464nm for 1mM(RCF1:9), 492nm for 3mM(RCF1:9), 472nm for 5mM(RCF1:11). In the SEM analysis the SEM images reveled that the average grain size of 5RCF1:11AgNPs is ranging from 3μm - 4μm with spherical clusters, while in the EDAX analysis Ag (69.14 weight %), C(8.62 weight %) and O(22.24 weight%) elements are present in the synthesized silver nanoparticles of 5mM(RCF1:11). Which are further characterized by XRD, TEM etc.
