title: [The study on the effect of LBP on cleaning hydroxygen free radical by EPR technique].
abstract: OBJECTIVE
  To study the effect of Lycium barbarum polysaccharides (LBP) on cleaning hydroxygen free radical.
  
  
  METHODS
  EPR.
  
  
  RESULTS
  When the concentrations of LBP were 0.25 mg/ml and 1.0 mg/ml, the cleaning rates of LBP to hydroxygen free radical were 18.64% and 87.29%.
  
  
  CONCLUSIONS
  LBP in low concentration can obviously clean hydroxygen free radical, but its clearance ability in high concentration descends.
