Abstract :In this study, gold nanoparticles insert ignore into journalissuearticles values(AuNPs); were synthesized following a bioreductive route using extract of Eriobotrya Japonica leaf. For the synthesis of gold nanoparticles, firstly, leaves of Eriobotrya Japonica were collected from the Eastern Black Sea region insert ignore into journalissuearticles values(Akçaabat-TRABZON); in Turkey and dried. Secondly, 20 g of dried sample was shaken in 400 mL of distilled water for 180 min. and extracted in a laboratoary microwave device at 4 minutes, 600 W and left cooling. Lastly, different volume of leaf extract was mixed with aqueous solution of HAuCl4.3H2O insert ignore into journalissuearticles values(0,5 mM-2 mM ); and then mixture was heated at the power of 90 W for various time intervals by a household microwave. The synthesis reaction of gold nanoparticles was monitored using by a Shimadzu UVP-1240 spectrophotometer and light-yellow color of the solution changed to purple color, indicating the formation of AuNPs.
