The synthesis of metal and semiconductor nanoparticles is an expanding research area due to the potential applications for the development of novel technologies. In this work, we describe a cost effective and environment friendly technique for green synthesis of silver phyto nanoparticles and their antibiogram from 3mM silver nitrate solution through the extract of Switenia mahagony as reducing as well as capping agent. In the process of synthesising silver nanoparticles, we observed a rapid reduction of silver ions leading to the formation of stable crystalline silver nanoparticles in the solution. The herbal leaves and their medicinal properties were already discussed in varieties of ayurvedic studies. The synthesis of silver phyto nanoparticles were prepared by adding silver nitrate solution solution (3mM) to the plant extract. Nanoparticles were characterised using UV-Visible absorption spectroscopy, FTIR, XRD, XRF, TEM AND SEM analysis. The biomass of plants produces their nanomaterials by a process called bio mineralisation. It was concluded from the above studies that 3 mM concentration of silver nanoparticles showed the best concentration amongst the various concentrations prepared and also their characterisation showed that these nanoparticles synthesised were mostly globular in structure, and proved to have the functional groups in the terminal ends as well as showed sharp peaks by XRD studies.Keywords

Silver nanoparticles of different concentrations were synthesized from the medicinal plant Vernonia amygdalina biologically, as this technique is cost effective and environment friendly. The characterization of the silver nanoparticles was analysed by the UV-Vis Spectrophotometer, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy, X-Ray Diffraction (XRD), and Fourier Transform Infra Red (FTIR). The absorption spectra of silver nanoparticles studied using the UV-Vis spectroscopy, had an absorbance peak at 475nm, in all the three different concentrations (1mM, 3mM and 5mM) of silver nanoparticles. The silver nanoparticles have a 50-70nm size range and appeared to be dominantly spherical and were occasionally triangular. The XRD pattern revealed that these silver nanoparticles have a crystalline nature. The antimicrobial activity of these nanoparticles was studied against E.coli, S.aureus, P.aeuruginosa, and C.albicans. They appeared to have satisfactory inhibitions against the four mentioned microorganisms. Among the different concentrations used in the study, the 3mM (20mg/500μl distilled water) appeared to have the highest sensitivity.Keywords

The chemopreventive effect of Geraniol was evaluated in N-nitrosodiethylamine-induced experimental liver tumor in Wistar albino rats. In this study the animals were divided into four groups with 6 rats each and received treatments for 4 weeks. Group I served as control (untreated), Group II treated with N-nitrosodiethylamine (DEN) (200 mgkg, i.p.) and Phenobarbital (PB) (0.05%) in drinking water; Group III received Geraniol (250 mg/kg b.wt) in addition to DEN and Group IV treated with Geraniol only for four weeks. The administration of Geraniol in rats with DEN induced HCC rats (Group III) shows a significantly reduced level of liver serum marker (aspartate aminotransferase, alanine aminotransferase, acid phosphatase, alkaline phosphatase, lactate dehydrogenase, gammaglutamyl transpeptidase, alpha fetoprotein and 5'nucleotidase). These results are evident that Geraniol possesses protective effect against N-Nitrosodiethylamine (DEN)-induced Hepatocellular Carcinogenesis (HCC).Keywords
