灵芝多糖的研究进展

灵芝多糖是灵芝的主要活性成分，近年来以其独特的保健功能成为研究的热点。灵芝多糖结构如分子量、单糖组成和糖苷键类型等，对其活性影响很大，本文列举了灵芝多糖结构通用的检测方法。已有实验证实，灵芝多糖的生物保健功能主要体现在降血糖、降血脂、抗肿瘤、提高免疫力和抗氧化方面，由于固态栽培灵芝有诸多因素的制约，液体发酵培养成为获取灵芝多糖的主要手段，而液态发酵条件的优化研究主要集中于种子的培养、碳源氮源的选择及微量微量元素的添加。传统提取灵芝多糖的方法如热水浸提法、碱提取法，有提取时间长、提取效率不高的缺点，而利用超声波辅助提取多糖受到人们的关注，并和传统提取方法做了比较，显示了这种方法的广阔应用前景。

Research Progress of Ganoderma lucidum Polysaccharides

Ganoderma lucidum polysaccharides as the major bioactive components have been attracted tremendous attentions due to their unique health functions.Biological activities and health functions of polysaccharides from Ganoderma lucidum have close relationships with their chemical structures such as molecular weight,glycosidic bond type and polysaccharide composition.Extensive investigations reported that polysaccharides from Ganoderma lucidum played important roles in reducing blood glucose and blood lipid,anti...
