There are variety of effluents are dumped or directly discarded into atmosphere due to drastic industrialization which leads to damages in living organisms. To prevent many type of environmental defects our research group focused to synthesis material which degrades toxic substance like dyes with the help of ecofriendly synthesis. We have synthesized Tin oxide nanoparticles (SnO2 NPs) using aqueous extract of Catunaregam spinosa (C. spinosa) root barks. Bio-inspired synthesized SnO2 NPs were monitored by analytical characterization which inferred that SnO2 NPs resulted in shape of spherical, with size average of 47 +/- 2 nm. Further bio-green synthesized SnO2 NPs were subjected to degrade toxic Congo red dye, which results in higher percentage of degradation with the K value of 0.9212 which obeys pseudo-first order reaction kinetics. This report said to be novel due to null report on SnO2 NPs synthesized from C spinosa root bark aqueous extract which also stated to be simplest, cheaper and non-toxic while compare to other methods. Further to identify the metabolites which is present in the aqueous extract were identified through Gas Chromatography and Mass Spectrometry with methanol as a solvent results that 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one contains higher area percentage of 67.47 with the retention time (RT) of 18.660.
