摘要

褐藻多酚是从褐藻中提取出的新型海洋天然物质,具有生物活性和医药价值,因而对开发海洋药物具有重要意义。它与陆生植物单宁质的化学反应性能基本相同(Ogino,1962),因此可采用单宁质的测量分析技术对其进行分析。Temple(1982)认为单宁质的测量技术可分为容量分析、重量分析、比色分析和色谱分析,由于容量分析、重量分析方法缺乏化合物结构选择性,而色谱分析更适用于组分的分离,且操作条件复杂;因而目前国内外大多数国家采用美国分析化学协会(Association of Official Analytical Chemists,AOAC,1970)的比色分析方法,即使钨钼酸盐氧化酚类化合物形成有色的钼蓝复合物,然后作比色分析。本文采用此法对我国几种常见褐藻进行了多酚含量分析。

Abstract

Phlorotannins are polymers of phloroglucinol known only from brown algae with various bioactivities. Folin-Denis method was used to determine the contents of phlorotannins from some Chinese common brown seaweeds. The results showed that Sargassum was rich in phlorotannins, e.g. 2.8% (dry weight) for Sargassum kjellmanianum, 2.0 % (dry weight) for Sargassum fusiforme and can be good resource for phlorotannins extraction.
