Thenanoparticlessynthesiswere characterizedusing adifferentmethodsUv-Visiblespectrophotometer, infraredspectroscopyandXRD. Thefirstresult was found forthe size ofnanoparticlesandrelationshipwiththeconcentration ofFeCl3, the highconcentration (0.03 M) product the nanoparticleswith size 2.3 nmand thelowconcentrationproduct thenanoparticles with size 22.16 nm. The FTIR analysisconfirmedthe biosynthesisofnanoparticleswith absorption from 500 to 800 cm-1. The crystallinestructureofNPswasconfirmed by X-ray diffraction (XRD) analysis. The antioxidant properties of the obtainedbiomaterial were assessedin vitro, using theDPPH and PPM test.The Fe3O4showed highantioxidant activity againstthemto test. Theresultssuggest thatPhoenix DactyliferaLextractassisted tosynthesisNPs present promising antioxidantcapacityand hence haveanimportant interestinthe development of therapeutic agents against oxidative tissue injuries.enNanoparticules, Fe2O3,Gree synthesis,Phoenix Dactylifera.L,DPPH, DRXArticle
