石斛多糖的药用功能研究进展

Advances on pharmacological activities of polysaccharides from dendrobium species

石斛是中国传统名贵中药材,多糖是石斛的主要有效成分,其药用功能的研究起步较晚,但已有研究表明,石斛多糖具有明显的调节免疫力、抗氧化、抗衰老、抗肿瘤、抗白内障、保肝、抑菌及降低血糖等药用功能,还有抑制脂类氧化和稳定酸性饮料中蛋白质的作用,其众多的应用价值引起了学者的广泛关注。本文综述了近10年来石斛多糖的功能作用研究进展,旨在为石斛多糖的深入研究及其在医药和食品产业化的开发应用提供参考。

Dendrobium was a precious traditional Chinese herbal medicine. Polysaccharides were the main effective components of Dendrobium. The researches on medicinal function of Dendrobium Polysaccharides had a late start. However,recent researches had shown that the polysaccharides from Dendrobium species have remarkable pharmacological functions,such as immunoregulation,anti oxidation,anti aging activities,antitumor,anticataract activities,hepatoprotective activities,antibacterial and hypoglycemic effects. They also improve such functions on the oxidation of liquid as the inhibitory effects,the effects on the stability of the milk protein under acidic conditions,and emulsifying properties of polysaccharides. The applied value of Polysaccharides caused extensive concern of numerous scholars. In this paper,the recent10-year advances on pharmacological functions and extraction techniques of polysaccharides from Dendrobium species internationally were reviewed. So it can provide some references for the future research and development of polysaccharides from Dendrobium species in both food industry and medicine industry.
