摘要
目的 :探讨枸杞多糖清除自由基的作用。方法 :采用电子顺磁共振技术 (EPR)检测不同浓度枸杞多糖对·OH自由基的清除作用。结果 :枸杞多糖清除·OH自由基的能力在 0 2 5mg/ml为 18 6 4 % ,在 1 0mg/ml为87 2 9% ,再增大浓度时清除能力呈下降趋势。结论 :枸杞多糖低浓度时具显著清除·OH自由基作用 。
Objective: To study the effect of Lycium barbarum polysaccharides(LBP) on cleaning hydroxygen free radical. Methods: EPR. Result: 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%. Conclusion: LBP in low concentration can obviously clean hydroxygen free radical, but its clearance ability in high concentration descends.
