An investigation of anti-oxidative compounds from the brown alga Dictyopteris undulata has led to the isolation and identification of isozonarol, isozonarone, chromazonarol, zonaroic acid and isozonaroic acid. Their structures were identified by comparison of MS and NMR spectra. Full NMR assignment and absolute configuration of isozonaroic acid are described. Isozonarol showed the most potent 1,1-
对来自褐藻 Dictyopteris undulata 的抗氧化化合物的研究导致了异唑酮、异唑酮、chromazonarol、zonaroic acid 和 isozonaroic acid 的分离和鉴定。通过比较 MS 和 NMR 光谱确定了它们的结构。描述了异环芳酸的完整 NMR 归属和绝对构型。Isozonarol 在分离的化合物中显示出最有效的 1,1-二苯基-2-picrylhydrazyl (DPPH) 自由基清除活性。
