Abstract

The objective of present research work focused on green methodologies for the synthesis of Schiff bases. The utilization of green chemistry techniques are considerably reduces the chemical wastes and reaction time. To illustrate these advantages, the present synthesis was introduced. This involves in the synthesis of Schiff base using natural acid catalyst. Here in we reported the synthesis of Schiff base from amino acid with carbonyl compound via natural acid prepared from citrus sinensis and solanum lyopersicum. The synthesized product was identified by its physical properties like melting point, molar conductance and UV-Visible, FTIR and XRD spectral techniques. Biological studies like antibacterial, antifungal, antioxidant and larvicidal was carried out for the synthesized Schiff bases. Compared with conventional methods, these methods were more fitting and provided higher yield, shows maximum efficiency, held without generation of pollution in shorter reaction time, safer to analyst, low cost and simple to run.
