Antioxidant Capacity Assessment of Plant Extracts for Green Synthesis of Nanoparticles

In this work, water extracts from different bio-based products of plant origin were studied to evaluate their antioxidant capacity and potential form metal nanoparticles aqueous solutions. Two traditional tests, the Folin–Ciocalteu assay DPPH radical scavenging method compared with a more recent one, SNPAC, based on formation silver nanoparticles. The nanoparticle (SNPAC) was optimized for its application in characterization selected work; kinetic studies extract concentration also evaluated. obtained leaves oak, eucalyptus, green tea, white common thyme, cedar, mint, rosemary, bay, lemon, seaweed Sargassum muticum. results demonstrate that any these three methods can be used as quick test identify an employed formation. Additionally, we synthesis Cu, Fe, Pb, Ni, Ag using eucalyptus demonstrating efficiency metallic salt Metal characterized by transmission electron microscopy dynamic light scattering techniques.
