| 摘 要： | 目的：研究南五味子粗多糖清除自由基能力。方法：采用热水浸提法从南五味子中提取粗多糖。用Vc作对比，采用化学比色法测定南五味子粗多糖在体外抑制DPPH自由基的能力；清除羟自由基（·OH）的能力；清除超氧自由基的能力（O2-·）。结果：在这三种自由基体系中，南五味子粗多糖均有清除能力，但结果因自由基体系的不同而能力不同，其IC50值分别为0．43mg／mL（DPPH·）、3．28mg／mL（·OH）以及14．81mg／m（O2-·）。结论：南五味子粗多糖具有较好的清除自由基性能。

| Abstract: | aim： To investigate the scavenging free-radicals activity of the coarse polysaccharides in fructus S. sphenanthera （CPSS） in vitro. Method： CPSS was extracted with hot-water. Colorimetric method was used to determined the scavenging effects on DPPH, ＇OH and 02 different. The IC50 were 0.43 anticxidant effects Result： In different free-radical systems, CPSS all had anticxidant effects. But the effects were mg/mL （DPPH＇）, 3.28mg/mL（.OH） and 14.81mg/mL（O2 -）. Conclusion： CPSS had potent |
