Couroupita guianensis, Silver nanoparticles synthesis of Plant extract were confirmed by UV-vis and FTIR. Further it was tested against various pathogenic microorganism and followed by antioxidant properties. The Couropita guinanensis flower extract mediated nanoparticles showed absorbance peaks at 318--323nm region in the spectral analysis.Fourier transform infrared spectroscopy analysis of the silver nanoparticles showed absorption peaks of reduced silver at 1631.95 cm−1. At concentration of plant extract with silver nanoparticles. The (12 mm) clear inhibitory zone appeared around 100µl against Pseudomonas aeroginosa MTCC 2453after incubation for 24h followed by Bacillus subtilis MTCC121 (23 mm), Staphylococcus aureus MTCC96 (13 mm), Klebsiella pneumonia MTCC109 (15 mm) and E.coli MTCC 912 (20 mm).In Couroupita guianensis total antioxidant was found to increase with increase in concentration in standard, plant extract and AgNO3.

 

Keywords: Couroupita guianensis, FTIR, UV and Antioxidant.
