1.灵芝多糖灵芝的多种药理活性大多和灵芝多糖有关,目前已分离到的灵芝多糖有200多种,其结构多呈螺旋状立体结构,其立体构型和DNA、RNA相似。含有葡萄糖,多糖链由三股单糖链构成,相对分子质量从数十至数十万道尔顿。除一小部分小分子多糖外,灵芝多糖大多不溶于高浓度酒精,但能在热水中溶解,因此,提取灵芝有效成分都采用热水提取法,方法简单,且提取产量高。从结构看,灵芝多糖大多为异多糖,除含有葡萄糖外,大多还含有少量的阿拉伯糖、木糖、岩藻糖、鼠李糖、半乳糖等其他单糖。结构不同,药理活性也不同,有的灵芝多糖甚至没有活性,有
1. Ganoderma lucidum polysaccharide Ganoderma most of the pharmacological activity and Ganoderma lucidum polysaccharides, there are currently more than 200 kinds of Ganoderma lucidum polysaccharide, the structure of mostly helical three-dimensional structure, the three-dimensional configuration and DNA, RNA similar. Contains glucose, polysaccharide chain consists of three monosaccharide chains, the relative molecular mass from tens to hundreds of thousands of Daltons. Except for a small part of small molecule polysaccharides, Ganoderma lucidum polysaccharides are mostly insoluble in high concentration of alcohol, but can be dissolved in hot water. Therefore, extraction of active ingredients of Ganoderma lucidum is hot water extraction method, the method is simple, and the extraction yield is high. From the structure, mostly Ganoderma lucidum polysaccharides polysaccharides, in addition to containing glucose, most also contain a small amount of arabinose, xylose, fucose, rhamnose, galactose and other monosaccharides. Different structures, pharmacological activity is also different, and some Ganoderma lucidum polysaccharides even without activity, there
