Results carnosine has a better protection than mannitol, benzoate, etc. in the Ascorbate-Fe(superscript 2+) system. Its antioxidative curve is similar to that of imidazole.

结果 在此实验条件下肌肽的抗氧化能力明显优於苯甲酸钠等常用抗氧化剂，其抗氧化动力学曲线与咪唑相似。

Ergothioneine is a kind of precious amino acid, and it is also a natural antioxidant. It plays an important role to prevent the oxidative damage in organism. Ergothioneine cannot be biosynthesized in humans, only can be absorbed from the diet. In recently the research discovered the high content of ergothioneine in the mushroom. Content of ergothioneine of Pleurotus eryngii is the highest from 28 kinds of mushrooms, therefore the research untilized P. eryngii to make the products of P. eryngii-fermented adlay and P. eryngii-fermented buckwheat which content high ergothioneine. Also, we analyzed their proximate composition, nutritional components, taste and physiologically active components, antioxidant properties and evaluation of anti-imflammatory effect.

中文摘要麦角硫因为一种稀有的胺基酸，也是天然的抗氧化剂，其在生物体内对氧化压力伤害之预防扮演著重要角色，麦角硫因不能在动物体内合成，仅能由食物中摄取，近年来发现在菇类中含有高含量的麦角硫因，从28种食药用菇类中筛选出麦角硫因含量较高的菌种，以杏鲍菇子实体最高(1521.6 mg/g dw)，因此本论文以杏鲍菇为媒介，利用固态发酵方式，制备出高麦角硫因之杏鲍菇薏仁和杏鲍菇荞麦，并针对薏仁、杏鲍菇薏仁、荞麦、杏鲍菇荞麦和杏鲍菇菌丝体，进行一般成分、营养、物性、呈味、生理活性物质、抗氧化性质之分析及抗发炎反应之评估。

Objective: In order to investigate the relationship among microbiotic antioxidant、free radical metabolism and reproductive ability, to discuss free radical metabolism influence the body growth as well as the development of organs.

目的：本试验通过微生物源性抗氧化剂和LPS对机体自由基代谢水平进行调控，研究微生物源性抗氧化剂、自由基代谢和机体繁殖性能的关系，探讨自由基水平对机体的生长发育、器官发育以及性发育等的影响，从而实现通过营养调控技术提高机体的繁殖性能。

The highest total flavonoid rate was 1.127%. An all-round evaluation for the antioxidant activity of the flavonoids extract from zizania-bract was carried out with that of ascorbic acid as the control. The evaluation indexes included the cleanup rate of the polyphenolic extract towards superoxidized anionic radicals, hydroxyl radicals, DPPH free radicals, the deoxidizing ability, and the antioxidant activity towards the peroxidize of lipids and edible oils.

采用抗坏血酸作为对照，全面测定了茭白苞叶总黄酮对超氧阴离子自由基、羟基自由基、DPPH自由基的清除率，以及还原能力、抗脂质过氧化活性和对食用油脂的抗氧化性的影响，结果表明，白苞叶中的总黄酮是一种有开发价值的天然抗氧化剂。

The larvae on different development stage indicated different sensitivity to reactive oxygen species, the napuli VI showed the most sensitive. 2 Antioxidants could decrease the damage effect of reactive oxygen species on larvae in certain level.The addition of antioxidants in culture system had risen larva suvival rate and the metamorphosis rate of cyprid .

外源抗氧化剂的加入在一定程度上减弱了活性氧对东方小藤壶幼虫的伤害作用，从而提高了幼虫的存活率和变态率；在减弱活性氧对东方小藤壶幼虫的伤害作用中，不同类型的抗氧化剂对不同类型的活性氧所起的作用大小不同。

People who have OA and eat large amounts of antioxidants in food have been reported to exhibit a much slower rate of joint deterioration, particularly in the knees, compared with people eating foods containing lower amounts of antioxidants.

人们有OA和谁吃的食物抗氧化剂大量已报告展示在膝盖关节恶化的速度要慢得多，特别是与人的饮食食品含有低量的抗氧化剂。

Influence of the antioxidants vitamin E and idebenone on retinal cell injury mediated by chemical ischemia, hypoglycemia, or oxidative stressRego A, SantosM, Oliveira C.. Free Radic. Biol. Med, 1999, 26: 1405 - 1417Abstract:A role for the antioxidants vitamin E and idebenone in decreasing retinal cell injury, after metabolic inhibition induced by chemical ischemia and hypoglycemia, was investigated and compared with oxidative stress conditions.

对由于化学贫血与低血糖所引起的代谢抑制后，抗氧化剂维生素E与艾地苯醌视网膜细胞受损所引起的作用进行了研究，同时并与氧化应激情况进行了对比，对氧化物维生素E(20 microM)和艾地苯醌(10 microM)进行先期培养可以在氧化应激或低血糖后防止视网膜细胞受损，而对上述二种抗氧化剂给予预先培养后带来的保护作用则有所减低。
