【摘要】 褐藻多酚的季节变化研究具有重要的理论意义。对海黍子和鼠尾藻 褐藻多酚的含量测定结果表明，褐藻多酚含量的季节变化范围分别在１．５～ ３．１％之间以及 ０． ８～ １． ８％之间。另外， ＰＶＰ吸附率也有相应的变化，分别在 ５１～６９％之间以及４１～６３％之间。更多还原

【Abstract】 In this paper, seasonal changes of content of phlototannins have been determined by Folin-Dents method and PVP absorption rate. The results showed that seasonal changes of contents of phlorotan- nins are between 1. 5-3. 1 % (dry weight) for Sargasnam kjellmanianum, 0. 8-1. 8% (dry weight) for Sargassum thunbergii, PVP absorption rates are between 51-69 % and 41-63 % respectively.更多还原
