Biogenic synthesis of gold nanoparticles using Haematocarpus validus fruit ethanol extract and their antioxidant activity

Abstract

 In order to obtain environmentally friendly nanoparticles for the biological applications, this paper explores the green route for the synthesis of gold nanoparticles via sonic bath method using Haematocarpus validus fruit extract as reducing, capping and stabilizing agent. The phytochemical screening of ethanol extract reveals secondary metabolites like anthocyanins, polyphenol, flavonoids, alkaloids and tannins. The prepared gold nanoparticles (HVGNP) were analysed using UV, FTIR, XRD, EDX and FESEM spectroscopic techniques. The antioxidant activity of synthesized HVGNP measured by the DPPH method reveals the synthesized gold nanoparticles appreciable antioxidant activity.
