Silver nanoparticles (AgNPs) were produced utilizing the aqueous extract of Colubrina asiatica (C. asiatica) and AgNO3 solution. The absorption spectra, morphology and size were analyzed using UV-vis spectroscopy, transmission electron microscopy and dynamic light scattering method, respectively. The effect of various parameters i.e., reaction time, AgNO3 solution concentration, extract concentration and reactants ratio on the synthesis of AgNPs were studied. It was found that 24 hours were required for the conversion of Ag⁺ ions into AgNPs at room temperature. However, more than 72 hours were needed to complete the reaction. The synthesized AgNPs were found to be spherical with average size 79 nm. It can be concluded that C. asiatica could be utilized for the production of AgNPs with acceptable size and shape.
