چکیده
Moringa leaf potentially has a high antioxidant becouse it contains secondary metabolite, one of which is quercetin. Therefore, to avoid harmful chemicals in the synthesis silver nanoparticles, made by using bio reductant extract. This study aims know optimal temperature formation characterize nanoparticle, and rest AgNPs DPPH method. laboratory experimental study. The nanoparticles uses concentration 0,4% extract, reacted AgNO3 with 1 mM ratio 1:9 at various temperatures 60oC, 70oC, 80oC for 30 minutes. formed are characterized UV-VIS spectrophotometry showing optimum formation, 80oC. It then continued PSA average size 80oC, 82,9 nm PDI value 0,225. result calculation IC50 shows that obtains 61.78 ppm, included strong category, meanwhile thick extract without addition obtain 124.41 weak category.
