Abstract: Brown seaweeds polysaccharide usually contains alginate, fucoidan, laminam and mainly exist in brown seaweeds. As the main physiological active substances, fucoidan composes of L-fucose and sulfate groups. Fucoidan has different beneficial biological activities including antioxidant, anticoagulant, anti-cancer, anti-tumor, anti-virus and anti-inflammatory, etc. This paper reviewed the latest research progress of the extraction procedures and bioactivities of fucoidan, which was expected to provided reference for fucoidan application.

Key words: brown seaweeds polysaccharide, fucoidan, extraction, bioactivities

摘要： 褐藻多糖是海藻胶、褐藻糖胶和褐藻淀粉的统称，主要存在于褐藻中。褐藻糖胶作为其主要的生理活性物质，主要由L-岩藻糖和硫酸酯基组成，具有抗氧化、抗凝血、防癌抗肿瘤、抗病毒和消炎等活性。综述了褐藻多糖的提取分离方法和褐藻糖胶的生理活性研究进展，以期为褐藻多糖的应用提供参考。
