title: Synthesis and antioxidant activity of star-shape phenolic antioxidants catalyzed by acidic nanocatalyst based on reduced graphene oxide.
abstract: Phenolic antioxidants play important role in prevention of oxidation in different industrials. The research objective in the current study was synthesis and evaluate of antioxidant activity of star-shape phenolic antioxidants. The synthetic compounds were prepared in the presence of sulfonated reduced graphene oxide. The antioxidant activity of synthesized compounds was investigated by spectrophotometrically method according to the DPPH assay. Overall, these compounds are potentially important antioxidant and also to limit activity of reactive oxygen species.
