在对褐藻总邻苯二甲酸单宁库结构多样性的研究中，我们首次在任何藻类中(通过溶剂分配和核磁共振实验)证明，螺旋藻同时产生岩藻醇和岩藻酚两种类型的聚合邻苯二甲酸。这些组分表现出比抗坏血酸和单体间苯三酚更强的抗氧化活性，间苯三酚是聚合间氯单宁的组成部分。岩藻醇和岩藻醇的抗氧化活性没有显著差异。
In a study of structural diversity in the total pool of phlorotannins in brown algae, we have shown, for the first time in any alga (by means of solvent partition and NMR experiments), that Fucus spiralis has simultaneous production of two types of polymeric phlorotannins of the fucol and fucophlorethol classes, respectively. These components exhibited a greater antioxidant activity than ascorbic acid and the monomer phloroglucinol, a constitutive of the polymeric phlorotannins. No significant differences in antioxidant activity were observed between fucol and fucophlorethol.
