Abstract
The invention relates to a Chinese angelica polysaccharide, which is made in the following way: dissolve alcohol deposit of Chinese angelica into distilled water, use savage method to more the protein away until there is no protein absorption peak of 280 nm by ultraviolet test, centrifugation to clear the deposit; keep the water-phase and add into alcohol for depositing polysaccharide, abandon the supernatant liquid, wash the deposit by alcohol, then freeze and dry it, through gel molecular chromatography, accumulate the separated product with the relative molecule mass between 10,000-110,000, then freeze and dry it again to acquire the Chinese angelica polysaccharide. The invention has remarkable analgesia for ache caused by chemicals and hot simulation; as well as dysmenorrheal caused by female hormone; and it can be made into drug for analgesia especially that for curing dysmenorrheal.
Description
Technical field
The present invention relates to a kind of Radix Angelicae Sinensis polysaccharide and its production and use.
Background technology
The angelica tonic is the dry root of umbelliferae (umbuiferae) angelica per nnial herb Radix Angelicae Sinensis [AngelicaSinensis (Oliv) Diels].Radix Angelicae Sinensis has benefiting blood and regulating blood circulation, and is promoting blood circulation and removing blood stasis, and the effect of menstruction regulating and pain relieving is often used Radix Angelicae Sinensis and other medicines compatibility according to disease clinically, is used for diseases such as menoxenia, dysmenorrhoea, headache due to deficiency of blood, waist abdomen pain.
The chemical constitution of Radix Angelicae Sinensis comprises volatile oil and water soluble ingredient two parts.Early stage research was once pointed out Radix Angelicae Sinensis oil to various animal isolated uterines, no matter the person of becoming pregnant or unpregnancy person have the effect of relaxing.It has made explanation for Radix Angelicae Sinensis is used for dysmenorrhea treatment to a certain extent.
Radix Angelicae Sinensis polysaccharide is present in the Radix Angelicae Sinensis water soluble part, the homology mixture that it is made up of the different macromolecular compound of molecular weight.In recent years, Radix Angelicae Sinensis polysaccharide has been proved to be has complicated biological activity, can regulate body's immunological function, the caused inhibition of antagonism cortin, prevent the minimizing of peripheral leukocytes and the irradiation ultimate effect in the radiation injury, enhancing body hemopoietic function and antitumor action.
Pain is common clinical symptom, and seek non-safely and effectively addicted analgesics thing is the problem that the medicine worker attaches great importance to always." dysmenorrhoea " be common gynecological disease especially, and the traditional Chinese medical science thinks that its pathogeny mainly is a QI and blood being obstructed, due to the hematogenous blockage.How Radix Angelicae Sinensis searches out its effective therapeutic component to carry out modernization of Chinese medicine reform as gynaecology's key medicine of the traditional Chinese medical science, makes it meet the modern formulation requirement, is the research focus of medicine educational circles.
" Chinese Pharmaceutical Journal " 2002; 37 (10): 746-8 " research of Radix Angelicae Sinensis Crude polysaccharides experiment of analgesic " discloses the Radix Angelicae Sinensis Crude polysaccharides and has analgesic activity, but sugared content is relatively low in the used Radix Angelicae Sinensis Crude polysaccharides, also contain other composition, and analgesic effect is not obvious.
Summary of the invention
Problem to be solved by this invention provides a kind of Radix Angelicae Sinensis polysaccharide preparation method and purposes, and the gained Radix Angelicae Sinensis polysaccharide has obvious analgesic activity, and especially treatment " dysmenorrhoea " has obvious effects.
Technical scheme provided by the invention is: a kind of Radix Angelicae Sinensis polysaccharide is made by laxative remedy: the angelol hypostasis is dissolved in distilled water, does not have the protein absorption peak of 280nm, the centrifugal precipitation of removing with Sevag method Deproteinization until ultraviolet detection; Keep water, add dehydrated alcohol, the precipitation polysaccharide is abandoned supernatant liquor, the gained throw out is with absolute ethanol washing, and after lyophilize, the gel molecular exclusion chromatography separates, and collects the relative molecular mass scope 1,0000-11, the separated product between 0000 obtains Radix Angelicae Sinensis polysaccharide again after lyophilize.
The present invention also provides the preparation method of above-mentioned Radix Angelicae Sinensis polysaccharide, and the angelol hypostasis is dissolved in distilled water, does not have the protein absorption peak of 280nm, the centrifugal precipitation of removing with Sevag method Deproteinization until ultraviolet detection; Keep water, add dehydrated alcohol, the precipitation polysaccharide is abandoned supernatant liquor, the gained throw out is colourless with absolute ethanol washing to washings, discard washings, the throw out after the washing is through lyophilize, and the gel molecular exclusion chromatography separates, collect the relative molecular mass scope 1,0000-11, the separated product between 0000 obtains Radix Angelicae Sinensis polysaccharide again after lyophilize.
Above-mentioned raw materials angelol hypostasis among the present invention can be used extracting method gained angelol hypostasis always from Chinese medicinal materials in the Chinese medicine preparation process: promptly Radix Angelicae Sinensis obtains water extract through poach, the throw out of water extract behind extraction using alcohol.
The resulting above-mentioned Radix Angelicae Sinensis polysaccharide of the present invention belongs to polymkeric substance, the representative of its molecular weight be similar chain length on average join cloth.Physico-chemical property through identifying Radix Angelicae Sinensis polysaccharide of the present invention is: the relative molecular mass scope is 1,0000-11, (adopt gel permeation chromatography-laser light scattering coupling technique) between 0000, soluble in water, sugar content is greater than 95%, detect through HPLC and to show mainly and forms, and ultra-violet absorption spectrum demonstration 192nm place there is obvious absorption peaks by glucose, pectinose, semi-lactosi, rhamnosyl and wood sugar; Infrared absorption spectrum analysis is at 3352cm
