Ruthenium nanoparticles (Ru NPs) of different sizes prepared using leaf extracts of fishtail fern (Nephrole-pis biserrata), sago palm (Cycas revoluta), rosy periwinkle (Catharanthus roseus) and holy basil (Oci-mum 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 nano-particles and plant groups has also been established.Keywords

Professor Raghunath Prasad Rastogi was born on 4 June 1926 in Lucknow to Purushottam Das Rastogi and Ram Janaki. Raghunath performed exceedingly well in the high school and intermediate examinations. Then completed his B Sc in 1946 and later B Sc (Hons) and M Sc from Lucknow University securing first positions in 1947 and 1948 respectively. In 1952, he obtained Ph D in chemistry under the supervision of A. C. Chatterjee on ‘Studies on physical properties of supernatural solution’.Full Text
