[The study on the effect of LBP on cleaning hydroxygen free radical by EPR technique].
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.
