Abstract

Pleurotus ostreatus (P2) was the fungus isolated from Iraq and identified in this study, then mycosynthesis of silver nanoparticles from aqueous extract of Pleurotus ostreatus (P2) at (10) mg/ml. The antioxidant activity for synthesized silver nanoparticles from aqueous extract of fruiting body of Plurotus ostreatus (P2) at concentration (10) mg/ml, in reducing power, total phenolic compounds and chelating ability were (5.33±0.11)nm, (13.80±0.10) mg/g and (85.36±0.55%) respectively. Reducing power for aqueous extract of fruiting body for Pleurotus ostreatus (P2) at concentration (10) mg/ml was (0.8±0.05) nm, total phenolic compounds (1.8+0.1) mg/g and chelating ability (26.10+0.10%), least significant differences (2.301).

Keywords: Pleurotus ostreatus, fungus isolated.
