In order to investigate the antioxidant activity and its characters of bleeding sap of V. vinifera from hotan, Sinkiang, its scavenging activities on freeradicals, its inhibitory effects on hemolysis of red blood cells, and the stabilities of its. OH scavenging activity to temperature and oxygen etc. were studied in this paper.

为检测新疆和田红葡萄伤流液的抗氧化活性和抗氧化特性，用体外检测法检测了该伤流液对OH、O2和DPPH等自由基的清除能力、对本质上由自由基介导的红细胞溶血的抑制、以及清除OH能力的温度和空气稳定性。

The more the number of hydroxyl substitution in phenyl ring, the better the ability of scavenging DPPH free radical. That is, trihydroxy is better than dihydroxy, and dihydroxy is better than monohydroxy. Moreover, when the polyhydroxy exists in phenyl ring and it is ortho-position or para-position, the ability of scavenging DPPH free radical is better too.

当苯甲醯基的苯环上羟基取代数量越多，其清除DPPH自由基的能力越好，三羟基效果优於双羟基、单羟基，双羟基效果优於单羟基；而苯甲醯基苯环上若为多羟基且羟基的位置为邻位或对位的关系时，其在清除DPPH自由基的能力较佳。

Antioxidant activity of Se-PC was investigated and compared with phycocyanin by using four different free radical scavenging assays, namely, trolox equivalent antioxidant capacity assay, DPPH free radical scavenging assay, superoxide anion scavenging assay and assay for erythrocyte hemolysis mediated by peroxyl free radicals .

通过含硒藻蓝蛋白与藻蓝蛋白对4种不同的自由基清除能力的比较，即总抗氧化能力、清除DPPH自由基、过氧化物阴离子和引发红细胞溶血的过氧化氢自由基能力测定，从而对含硒藻蓝蛋白的抗氧化活性进行评价。

The scavenging effects of different solvent extracts on hydroxyl radicals produced by the system were compared by phenanthroline oxidation method, and change conditions of scavenging rate of hydroxyl radicals with the prolonging of time were studied.

方法］采用超声波提取法，分别以蒸馏水、50%乙醇和95%乙醇为溶剂，在40℃条件下提取30 min，获得了薄荷的不同溶剂提取物，并以邻二氮菲氧化法比较了不同溶剂提取物时体系产生的羟基自由基的清除作用，并研究随时间延长羟基自由基清除速率的变化情况。

Glycyrihizic acid can cause the polarigraphic catalytic wave of oxygen. GA scavenging superoxide ion is demonstrated chemically by the catalytic wave at molecular lever.

本文报道的甘草酸及其皂甙类衍生物存在下的氧极谱催化波，从分子水平研究了GA清除超氧离子自由基〓的化学作用机制，证实清除〓的活性基团是GA分子中与C＝O基共轭的C＝C双键，并非-OH基，纠正了文献观点。

The results show that the penetration ratio decreases with increase of filtration velocity, the range of the most penetrating particle size is in the range of 0.15～0.20 μm, the effect of aerosol concentration on the filtration efficiency is ignore for monodisperse, the filtration efficiency of each step on multilayer is different from others for polydisperse.

研究结果表明：用玻璃纤维膜过滤清除气溶胶团粒时，对粒径在 0 15～ 0 。2 0 μm之间的团粒较难清除；透过率随流速的增加而增加；单分散气溶胶团粒浓度变化对过滤效率的影响可忽略不计；多级过滤时，各单级过滤效率差异受多分散气溶胶的影响较大。

Seedlessness treatments increased the contents of polyphenols and antioxidant capacity in leaf, stem and tentril, while decreased them in skin and pulp.

4无核处理提高了叶片、茎和卷须内酚类物质的含量及其清除自由基的能力，而果皮和果肉中含量有所下降，相应的清除自由基的能力也低于对照。
