Abstract

Irigenin, an isoflavone (mol. formula = C18H16O8), was isolated from the plant Iris hookeriana using dichloromethane as solvent. The compound was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible spectroscopy measurements. Structural analysis of XRD data confirmed the orthorhombic structure for the compound. The microstructure of the compound is an aggregate of microcrystals with an irregular morphology. From the UV-visible spectroscopy, the present compound shows indirect allowed transition with an optical band gap (Eg) of around 3.25 eV. The present optical properties of the compound can be utilized in flexible organic electronics applications.
