Description
Technical field
The present invention relates to a kind of glutinous rehmannia and extract the method for rehmannia root oligose, Dihuang polysaccharide.
Background technology
Glutinous rehmannia is a kind of Chinese medicinal materials, has another name called the dried rhizome of rehmannia, and sweet-bitter flavor is cold in nature; Heat-clearing, promote the production of body fluid, moisturize, cool blood, hemostasis; The dried rhizome of rehmannia is further concocted the back and is cultivated land.The dried root of Shi Xuan Ginseng section plant bosom glutinous rehmannia.Effects such as that the dried rhizome of rehmannia has is nourishing Yin and clearing heat, cooling blood for hemostasis; Control deficiency of Yin low-heat, pyreticosis agitation, body fluid few, send out diseases such as spot dermexanthesis, hemoptysis, haematemesis, menoxenia, hematuria, uterine bleeding.The cultivated land flavor is sweet, warm in nature; Return liver, kidney channel; Effects such as nourishing YIN and supplementing blood strengthening and nourishing marrow and essence are arranged; Control diseases such as deficiency of Yin blood is few, the deficiency of blood is weak, the frightened dizziness of the heart, dim eyesight, emission due to deficiency of the kidney, deficiency of Yin hemoptysis, soreness of the waist and knees, uterine bleeding.Glutinous rehmannia contains multiple glycoside composition and carbohydrate, can extract rehmannia root oligose, Dihuang polysaccharide from glutinous rehmannia.Carbohydrate has the branch of polysaccharide, oligose, monose according to the difference of glycan molecule.It is all that can not to be hydrolyzed to more micromolecular sugar again be monose; The sugar of 10 above unit molecule compositions is polysaccharide; By 2～9 molecular sugar of monose then is oligose, claims oligosaccharides again.Dihuang polysaccharide has the effect that improves immunity function, suppresses tumour; Rehmannia root oligose can strengthen hemopoietic function and promote immunity, the effect of lowering blood glucose, can promote the hyperplasia of bifidus bacillus in the human intestinal, can be used for treating acute and chronic diarrhoea, hepatogenic encephalopathy, particularly the glutinous rehmannia oligose can and be regulated intestinal microecology and constipation is produced the comprehensive therapy effect by its hypertonicity, makes rehmannia root oligose, Dihuang polysaccharide are familiar with by people more and more and utilize.But the glutinous rehmannia of prior art is extracted the method complex technical process of rehmannia root oligose, Dihuang polysaccharide, cost of manufacture height.
Summary of the invention
