Summary:Ruthenium nanoparticles (Ru NPs) of different sizes prepared using leaf extracts of fishtail fern (Nephrolepis biserrata), sago palm (Cycas revoluta), rosy periwinkle (Catharanthus roseus) and holy basil (Ocimum tenuiflorum) in methanol exhibited pronounced antifungal (against Aspergillus flavus) and antioxidant activity (DPPH, ABTS, SO, OH). The synthesized Ru NPs were characterized using FTIR, UV-visible spectra, fluorescence and XRD. A tentative synthetic mechanism of NPs has been hypothesized via redox mechanism. A correlation between size of nanoparticles and plant groups has also been established.
