Antibacterial and Antioxidant Activity of Biosynthesized Silver Nanoparticles Produced by Aegle marmelos Fruit Peel Extract

In this work 1 mL, 5 mL and 10 mL of fruit peel extract were used in biosynthesis of AgNPs (a), (b) and (c), respectively. Phytochemical analyses of fruit peel extract demonstrated the presence of reducing agent such as steroids, flavonoids, polyphenolics, tannis, reducing sugar and amino acid compound. These compounds are confirmed by GC-MS analysis. Biosynthesized AgNPs were characterized by UV-Vis Spectra, Transmission Electron Microscopy (TEM), Selected Area Electron Diffraction (SAED), Fourier Transform Infrared Spectroscopy (FT-IR), and Zeta Potential. Biosynthesized AgNPs were shows an antibacterial property against gram negative Escherichia coli and antioxidant property. The higher value of zone inhibition observed by 12.5 & mu;g/mL of AgNPs synthesized with 10 mL of A.marmelos (L) have been observed to be 24 & PLUSMN; 0.9 mm. Bio-synthesized AgNPs (c) shows high antioxidant and antibacterial potency because of their monodisperse nature.
