Abstract

Conventional chemical synthesis of silver nanoparticles (AgNPs) can generate hazardous waste, encouraging the development of greener alternatives such as green synthesis using natural materials. This study analyzes the formation and characteristics of AgNPs from soursop leaf extract (Annona muricata L.) which function as reducing and stabilizing agents. Secondary metabolites in soursop leaves include tannins, flavonoids, saponins, and alkaloids, which contribute to the reduction of silver ions. The research involved ethanol maceration extraction, phytochemical screening, nanoparticles synthesis using an extract to AgNO₃ ratio of 1:20 at 600C for 1–2 hours, and characterization by UV–Vis and FTIR spectroscopy. A color change to dark brown confirmed nanoparticle formation. UV–Vis analysis showed an SPR peak around 390 nm, indicating small and stable particles. The functional groups in the FTIR results indicate involvement in reduction and stabilization. Overall, green synthesis using soursop leaf extract was successful and shows promise for biomedical applications.
