Abstract
The present invention relates to a process for extracting anthraquinone substances from aerial portion of rheum officinale plant. Said invented process is simple in equipment. Its solvent is cheap, and can be recovered and can be repeatedly used, its extracting efficiency of high, and the obtained extract is safe and its purity is high.
Description
Technical field
The present invention relates to the extraction process that a kind of Rheum plant shoot divides anthraquinones.
Background technology
Rheum officinale is the distinctive world-renowned traditional Chinese medicine of China, is Rheum plant sorrel, and the root and rhizome of Rheum officinale, Rheum tanguticum also is called genuine rhubarb, is recorded in Chinese Pharmacopoeia (version in 2000), is also collected by the pharmacopeia of many countries.Use rheum officinale and cure the disease, be recorded in the earliest in the Shennong Bencaojing,, sum up the drug effect of summarizing rheum officinale and be: eliminating fire and detoxication, attack long-pending stagnation resolvation, dissipating bind hemostasis etc. through the continuous practice and the application of ancient Chinese medicine doctor in the history in existing several thousand of China.In recent years, used the method repeated clinical practice and the experimental study of the combination of Chinese tradiational and Western medicine, further determined curative effect, enlarged the rheum officinale range of application, and be not only a kind of traditional tcm clinical practice prescription medicine commonly used, and be applied in the protective foods.Rheum officinale contains multiple biologically active substance (allied compounds such as catechin, gallic acid, anthraquinone analog compound, stilbene class, phenyl propyl ketone glucoside, tannin class) and is called as the Herba Chloranthi holostegii(Herba chloranthi japonici) of clinical Chinese medicine with genseng, cultivated land, monkshood.Rheum officinale have rush down down, resisting pathogenic microbes, protect the liver, cholagogic, reducing blood-fat, improve renal function, diuresis, reduction blood urea nitrogen, hemostasis invigorate blood circulation, antitumor, regulate many pharmacological actions such as immunity, cardiac stimulant, anti-stick film ulcer, along with the further investigation of its pharmacological action, the pharmaceutical use of rheum officinale is more and more higher.
Nearly 45 kinds of China Rheum plants except that the 2-3 kind, all have pharmaceutical use, concentrate to be distributed in a northwest and a southwestern band.In Qinghai, rheum officinale distributes and spreads all over the whole province.Rheum tanguticum mainly is distributed in states such as Golog, cajaput, Huang Nan, Hai Bei, Hai Xi, and also there is distribution in Xining.Sorrel mostly is the garden cultivation, and main concentrating is distributed in each county, Haidong Prefecture.Golog state wild resource standing stock account for 63% of the whole province's resource standing stock.
In the many physiologically active substances of rheum officinale, anthraquinone analog compound is main composition, comprises dissociated anthraquinone and combined anthraquinone.Earlier 1900s, the structure of main dissociated anthraquinone class material is understood in the rheum officinale, comprises rhubarb yellow, Schuttgelb, rhabarberone, chrysophanol, rheochrysidin etc.; To the sixties, found their a series of monose glucosides, DIANTHRAQUINONE class and their glucoside.
The root and rhizome of rheum officinale underground part is as a kind of medicinal material, use with a long history, and in the Chinese Minority Nationalities area with the custom of edible over-ground part tender leaf and petiole is abroad also arranged very early.When utilizing underground medicinal material, cause the waste of geodyte resource unavoidably, and the blade of over-ground part, anthraquinone class content is not low yet after measured for petiole, annual biomass is very big, if under the situation that does not influence plant normal growth,, pluck according to a certain percentage in suitable season, and be used, then can save many wildlife resourcess.At present, the series product of relevant rheum officinale are existing thousand kinds in the world, but still have the leeway of deep level development.
Of the present invention open
The objective of the invention is for a kind of extraction process of dividing anthraquinones from the Rheum plant shoot is provided.
Purpose of the present invention can realize by following measure:
A kind of Rheum plant shoot divides the extraction process of anthraquinones to comprise following processing step: get filter residue after dividing fresh petiole to squeeze the juice the rheum officinale plant shoot; Add 8-10 alcohol doubly in filter residue, 70-90 ℃ of following refluxing extraction 2 times, extraction time was followed successively by 1 hour, 0.5 hour, and united extraction liquid reclaims solvent and gets extracting solution.
Purpose of the present invention also can realize by following measure:
A kind of Rheum plant shoot divides the extraction process of anthraquinones to comprise following processing step: divide dry petiole to pulverize the rheum officinale plant shoot; Add 8-10 alcohol doubly in crushed material, 70-90 ℃ of following refluxing extraction 2 times, extraction time was followed successively by 1 hour, 0.5 hour, and united extraction liquid reclaims solvent and gets extracting solution.
The present invention has following advantage compared to existing technology:
1, technology of the present invention is simple and feasible, and required equipment is simple, cost is low.
2, the present invention utilizes the dissolution characteristics of anthraquinone substance, and the dissociated anthraquinone in the raw material can more fully be extracted.
3, the present invention carries out drying or the processing of squeezing the juice to raw material, can significantly reduce solvent load, reduces cost.
4, solvent safety of the present invention, inexpensive, can reuse.
Embodiments of the present invention
The present invention also will be described in further detail in conjunction with the embodiments:
Embodiment one:
Get the Rheum plant shoot and divide fresh petiole peeling, chopping, chopping in the high speed hollander, the back of squeezing the juice, filtration, the gained filter residue is placed container, add 6 times 80% medical alcohol, extract at 80 ℃ of following minute secondary backs, the time was followed successively by 1 hour, 0.5 hour, united extraction liquid, recovered alcohol, the gained extracting solution is anthraquinone substance in the rheum leave and stem, can be added in the health-care rhubarb food.
Embodiment two:
Get in the Rheum plant shoot branch drying anthraquinones and pulverized 50 orders, place container, add 8 times 75% medical alcohol, extract at 80 ℃ of following minute secondary backs, time was followed successively by 1 hour, 0.5 hour, united extraction liquid, recovered alcohol, the gained extracting solution is rheum rhabarbarum petiole anthraquinone substance, can be added in the health-care rhubarb food.
