对阿根廷海三种鱼卵中天然抗氧化剂Gadusol(3，5，6-trihydroxy-5-hydroxymethyl-2-methoxycyclohex-2-en-1-one)的含量进行了定量测定：阿根廷沙鱼(MerLuccius Hubbsi)、巴西沙鱼(Pguipes Brasilianus)和阿根廷沙鱼(Pusopcis Semifasciata)。在沙鱼中发现了该化合物的显著产量。用ORAC法和ABTS法测定了分离的代谢产物在水溶液中的抗氧化活性，并与其他已知的天然抗氧化剂进行了比较。结果表明，Gadusol是过氧基携带的链式反应的良好断裂剂。此外，其减少自由基的能力可与抗坏血酸相媲美。在此基础上，来自巴西和阿根廷沙鱼的鱼卵被认为是人类食用的有用的抗氧化剂来源。(C)2009爱思唯尔有限公司。保留所有权利。
The occurrence of the natural antioxidant gadusol (3,5,6-trihydroxy-5-hydroxymethyl-2-methoxycyclohex-2-en-1-one) was quantified in fish roes of three species from Argentine Sea: argentine hake (Merluccius hubbsi), brazilian sandperch (Pinguipes brasilianus) and argentinian sandperch (Pseudopercis semifasciata). Significant yields of the compound were found in the sandperchs. The antioxidant activity of the isolated metabolite in aqueous Solution was assessed by ORAC and ABTS assays and compared with that of other known natural antioxidants. The results indicate that gadusol is a good breaker of chain reactions carried by peroxyl radicals. Besides, its ability to reduce radicals is comparable to that of ascorbic acid. On this basis, fish roes from brazilian and argentinian sandpearchs are proposed as useful sources of antioxidants for human consumption. (C) 2009 Elsevier Ltd. All rights reserved.
