title: [Relationship between antioxidant activities and contents of active ingredients in Radix Scutellaria].
abstract: OBJECTIVE
  To study the relationship between the antioxidant activities and the contents of active ingredients in Radix Scutellaria.
  
  
  METHODS
  The antioxidant activities of extracts and active ingredients of Radix Scutellaria in NADPH-dependent lipid peroxidation in rat liver microsome were assayed.
  
  
  RESULTS
  Extracts of Radix Scutellaria showed a 50% inhibition of lipid peroxidation in the concentration range of 2.72-18.27 mg x L(-1).
  
  
  CONCLUSIONS
  The antioxidant activities of extracts of Radix Scutellaria are not only related with the contents but also the ratio of the active ingredients.
