Abstract

Background:  Poor solubility and bioavailability of herbal drugs, which are a barrier to their effective administration, can be resolved with the use of appropriate nanomaterials that will improve their pharmacokinetics.Aim:The aim of the current study is to analyse the synthesis of silver nanoparticles from red tea and ginger extract and to determine the antioxidant potential of it.Materials and Methods:  DPPH free radical scavenging assay and hydroxyl radical scavenging assay was performed to determine the antioxidant potential of red tea and ginger formulation mediated silver nanoparticles. The percentage inhibition of DPPH radical scavenging activity  and hydroxyl radical scavenging activity was calculated. The data was analysed statistically and the level of significance was considered at the level of p<0.05.Results: There is a dose-dependent increase in the percentage of inhibition of DPPH free radical and hydroxyl free radical by red tea and ginger formulation mediated silver nanoparticles. The percentage of inhibition increases with increase in the concentration of the extract. Conclusion: The study concludes that red tea and ginger formulation mediated silver nanoparticles have potent antioxidant properties and can be used as an herbal antidote for the treatment of various diseases due to  oxidative stress.
