| 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0.25 mg/ml为18.64%,在1.0 mg/ml为87.29%,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,但高浓度时其清除能力却下降.

| Abstract: | 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. |
