In this study, green synthesis of gold nanoparticles (AuNPs) using aqueous extract from Hymenaea courbaril resin (HCR) is reported. The successful formation, functional group involvement, size, and morphology the subject H. mediated (HCRAuNPs) were confirmed by Ultra Violet-Visible (UV-vis) spectroscopy, Fourier-Transform Infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM) techniques. Stable high yield HCRAuNPs was formed in 1:15 (aqueous solution: salt solution) reacted sunlight as indicated visual colour change appearance surface Plasmon resonance (SPR) at 560 nm. From FT-IR results, phenolic hydroxyl (–OH) found to be involved stabilization nanoparticles. TEM analysis showed that particles are highly dispersed spherical shape with average size 17.5 synthesized significant degradation potential against organic dyes, including methylene blue (MB, 85%), methyl orange (MO, 90%), congo red (CR, 83%), para nitrophenol (PNP, 76%) up 180 min. also demonstrated effective detection pharmaceutical pollutants, amoxicillin, levofloxacin, azithromycin environment observable changes color UV-Vis spectral graph.
