A team led by professor kim se - kwon of pukyong university in busan says it isolated a peptide with antioxidant properties from bullfrog skin 釜山釜庆大学金胜勋教授领导的研究小组称，他们从牛蛙的皮肤中分离出了一种具有抗氧化特性的生化肽。
Synthetic tendly oregano oil （ carvacrol ） oil of oregano has the properties of anti - bacterial ( gram - positive bacteria and gram negative bacteria ) , anti - coccidia and anti - oxidant activity 添德力牛至油（香芹酚）的生物活性几乎对所有重要的革兰氏阳性和革兰氏阴性菌都有活性，同时还有抗真菌、抗球虫和抗氧化特性。
Polyphenols hae much better antioxidant properties than itamins , and hae been the object of growing interest on the part of nutritionists , epidemiologists , agrifood firms and consumers oer the past decade or so 多酚类化合物比维生素有着更好的抗氧化特性，在过去的十年间，多酚类化合物已经逐渐引起了营养学家、流行病学家、农业食品公司及普通消费者的兴趣。
In order to find a new way to prepare antibacterial fibers , photocatalytic oxidation of titanium dioxide ( tio2 ) has been used to modify the surface property of polymers in our experiment . tio2 films are deposited on polyethylene terephthalate ( pet ) substrates by means of rf magnetron sputtering using pure ti ( 99 . 99 % ) as the target and ar mixed with o2 as reactive gas 本文利用磁控反应溅射技术，以高纯度钛( ti )为靶材，氧气为活性气体，在pet基底上反应溅射沉积tio _ 2 ，将纳米tio _ 2的光催化氧化特性应用于高聚物表面改性，为进一步开发抗菌织物打下基础。首次在高分子pet基底上溅射沉积了氧化钛薄膜。
