海带多糖是从双环海带中分离得到的。根据甲基化、高碘酸氧化、1H和13 C核磁共振谱，证明该葡聚糖具有由（1 → 3）-和（1 → 6）-连接的β-d-吡喃葡萄糖残基以3：2的比例组成的支链结构。通过比较其13 C和1H，特别对葡聚糖进行了表征。NMR谱图与相关化合物的NMR谱图。高碘酸氧化海带多糖后还原得到的多元醇多糖的NMR研究，对于阐明天然葡聚糖的组成、结构和主要序列非常有用。
Laminaran was isolated from Eisenia bicyclis. On the basis of the methylation, periodate oxidation, NMR spectroscopy by 1H and 13C nuclei, this glucan was shown to have a branched structure composed of (l → 3)- and (l → 6)-Iinked β-d-glucopyranose residues in the ratio 3: 2. The glucan was especially characterized by comparison of its 13C and 1H. NMR spectra with those of related compounds. The NMR investigation of the polyol polysaccharide, obtained by reduction after periodate oxidation of laminaran, was very useful for elucidation of the composition, structure and major sequence of the native glucan.
