海参多糖的提取分离与生物活性研究进展

海参自古就被视为营养圣品,具有保健与药用价值,现已成为功能性食品开发的重要方向。海参体壁中含有的多糖成分具有增强免疫力、抗肿瘤、抗凝血、延缓衰老、保护神经细胞、保肝等多种生物活性,可作为功能性食品的重要功能因子。海参多糖正逐步成为海洋生物活性物质综合利用的研究热点。但目前海参多糖的各种保健和抗癌机制尚不清楚,这是未来海参保健及抗肿瘤研究的重点与难点,对其机制深入研究具有重要的意义。海参多糖的常用提取方法主要有溶剂提取法与蛋白酶水解法,蛋白酶水解法是提取海参多糖的理想方法。海参多糖常用的分离方法有电泳、色谱分离法和分级沉淀法等。本文主要介绍海参多糖的常用提取分离方法及主要的生物活性,为海参功能性食品的研发提供参考。

Research progress on extraction, separation and biological activity of sea cucumber polysaccharide

Sea cucumber, regarded as nutritional supplements from ancient times, has health and medicinal value and it has become an important direction of functional food development. Sea cucumber body wall contains polysaccharide ingredients, with enhanced immunity, anti-tumor, anticoagulant, anti-aging, protection of nerve cells and liver, and other biological activities, can be used as functional factor. This paper mainly introduces the common extraction and separation method of polysaccharide from sea cucumber and its main biological activity, which can provide reference for the research and development of sea cucumber functional food.
