多糖是由醛糖或酮糖通过甙链连接在一起的多聚物,是一类广泛存在于高等植物、真菌、藻类、细菌和动物细胞膜上的生物大分子,是构成生命的四大基本物质之一.到目前为止,从天然产物中已分离出上百种多糖类化合物,其中中草药来源的水溶性多糖最多.多糖不但是生物体的主要结构成分,还具有复杂的生物活性和功能.现代研究表明,中药多糖具有激活巨噬细胞、T及B细胞、补体系统、NK细胞及抗肿瘤、抗病毒、降血糖等活性作用.许多补益类中药,如人参,其所含的多糖成分已被证明有免疫刺激调节作用.
Polysaccharide is a ketose aldose or linked through glycoside chain polymers, are a class of widely distributed in higher plants, fungi, algae, bacteria and animal cell membranes of biological macromolecules, constitute the four basic substances of life one. So far, from natural products have been isolated from hundreds of polysaccharide compounds, including herbal source of most water-soluble polysaccharide.Polysaccharide is not only the main structural components of living organisms, but also has a complex biological activity and function. Modern research shows that Chinese Herbs can activate macrophages, T and B cells, complement system, NK cells and anti-tumor, antiviral, Hypoglycemic effect of such activity. Many tonic herbs, such as ginseng, which contains polysaccharides have been shown to stimulate the immune regulation.
