Evaluation of Antioxidant Activity of Synthesized Silver Nanoparticles from Citrus
Aurantium Peels Extract by Using the Green Method
The substance which avoids oxidant of easily oxidizing substance even at low concentration is called antioxidant when antioxidant reacts with reactive oxygen species (ROS) or reactive nitrogen species (RNS) they often convert themself into antioxidant radical. Although such a radical has a reduced ability to react with imperative cellular targets, it can still cause damage. To decrease reactivity and reduction potential further down, the ‘antioxidant radical' react with another antioxidant and this reaction continues in a stepwise manner until antioxidant radical’ is no longer damage the cells like lipids, protein, DNA, and other important cellular molecules. In this research article, we had scanned our previously synthesized silver nanoparticles from Citrus aurantium peels extracts; Synthesis and characterization part of the research work is already in communication we are extending our research work on previously synthesized silver nanoparticles. In this research article, we had scanned the antioxidant activity of synthesized AgNPs was determined by H2O2 free radical scavenging activity, we obtained antioxidant activity of BHT with IC50 Value 65.52 µg/mL and antioxidant activity of synthesized AgNPs with IC50 Value 93.92 µg/mL. Antioxidant activity of synthesized AgNPs was also determined by DPPH free radical scavenging activity. We obtained antioxidant activity of BHT with IC50 Value 65.99 µg/mL and antioxidant activity of synthesized AgNPs with IC50 Value 99.68 µg/mL.
