title: In vitro antioxidant activities of Solanum surattense leaf extract.
abstract: OBJECTIVE
  To evaluate the antioxidant activity of alcoholic leaf-extract of Solanum surattense (Solanaceae) (S. surattense).
  
  
  METHODS
  Leaf extract were tested for in vitro free radical scavenging assays, such as hydroxyl radical and hydrogen peroxide, inhibition of superoxide anion radical and 2, 2-diphenyl-1-picryl hydrazyl radical (DPPH), total antioxidant activity and reducing ability. Further, total phenolic content of S. surattense was analyzed.
  
  
  RESULTS
  S. surattense extract effectively scavenged free radicals at all different concentrations and showed its potent antioxidant activity. Further, these effects were in a dose dependent manner. Results were compared to standard antioxidants such as butylated hydroxytoluene, ascorbic acid and α-tocopherol.
  
  
  CONCLUSIONS
  S. surattense have strong antioxidant potential. Further the study validates the therapeutic benefits of the Indian system of medicine.
