In this study, the biosynthesis of silver nano cubes was carried out using leaf extract of Peltophorum pterocarphum (P. pterocarphum) containing Quercetin-3-O-β-D-Galactopyranoside compound. Simple organic compound extraction and reaction with silver nitrate was carried out. Synthesized nano cubes were characterized by various  techniques like UV-Visible spectroscopy, Scanning Electron Microscopy (SEM), Fourier Transform Infra Red (FTIR) spectroscopy and X-Ray Diffractometer (XRD). The antifungal assay of silver nano cubes was performed, which shows potential effect on plant pathogenic fungi Rhizoctonia solani (R. solani). It shows increasing inhibitory action when compared to commercially obtainable anti fungal agent fluconazole. Thus for first time it was revealed that the active compound extracted helps in synthesis of silver nano cubes from the plant source and its application as an antimicrobial agent against plant morbific fungi.

Keywords: Silver nano cubes; Characterization; Quercetin-3-O-β-D-Galactopyranoside; P. pterocarphum; Antifungal activity.
