From the method for galloylpaeoniflorin, belong to Chinese medicine separation technical field of purification.
Background technology
Galloylpaeoniflorin English name Galloylpaeoniflorin, CAS：122965-41-7, molecular formula is
C30H32O15, molecular weight is 632.57, and structural formula is as follows：
。
Nearest research report points out that red paeonia extract has an impact to calcium ion concentration in maincenter cranial nerve.The radix paeoniae rubrathe is clinically
Apply in depression, antitumor, immunological regulation, protection blood vessel, protect liver etc., these and the invigorating the spleen described in Traditional Chinese medical theory
Correction gas, strengthen immunity are consistent.And the pharmacological activity test that foreign scholar makes of the extract of the radix paeoniae rubrathe, it is found that the radix paeoniae rubrathe has
Maincenter cranial nerve, be immunized, stimulate the menstrual flow, antiatherosclerosis, antineoplastic action.
Galloylpaeoniflorin is the class important activity compound having in the radix paeoniae rubrathe, is the characteristic chemical constituent of the radix paeoniae rubrathe.
The compound, which has, suppresses arachidonic acid（arachidonic acid AA）Generate the function of enzyme.Found in studying in vitro,
Galloylpaeoniflorin reduces hyperplasia rate with the pattern of dose dependent and time dependence, and inducing cell withers
Die.Galloylpaeoniflorin starts apoptotic signal by suppressing mitochondrial function, and apoptosis occurs for final cell.Therefore, from
Separating high-purity galloylpaeoniflorin is extracted in former plant, to quality of medicinal material Con trolling index, its pharmacological action is illustrated and is
New drug development is found lead compound and had great importance.
Monoterpene and saponin(e in Chinese medicine composition autonomic drug intermediate are disclosed in Publication No. CN104072550A application
The separation method of constituents：Obtained successively with petroleum ether, ethyl acetate, extracting n-butyl alcohol, purification with macroreticular resin 30% and
70% alcohol elution, take the isolated albiflorin R1 sterlings of 30% alcohol elution, Paeoniflorin sterling, take 70% ethanol to wash
The de- isolated Paeoniflorin lactone sterling in position, Chinese herbaceous peony ketoside sterling, benzoylpaeoniflorin sterling, galloylpaeoniflorin are pure
Product, methyl Paeoniflorin sterling, ginsenoside Rg1's sterling, Ginsenoside Rc's sterling, ginsenoside Rb1's sterling, ginsenoside Rb2
Sterling etc..Although this method can obtain galloylpaeoniflorin sterling, the purity of its galloylpaeoniflorin sterling is low, uses
Its technique is can not to obtain HPLC purity up to more than 98.5% monomer.
Publication No. CN1799581, moutan bark effective constituent and preparation method, the percentage composition of its active component is Chinese herbaceous peony
Glycosides 10~25%, galloylpaeoniflorin 40~55%, paeonoside 30~45%；Preparation method is will to add after root bark of tree peony pulverizing medicinal materials
Heat is extracted, and extract solution is condensed into medicinal extract, carries out mixing sample with silica gel, it is separated with normal phase silicagel column, and eluent is dense
Contracting obtains sample after drying, and continues isolated active principle with preparative liquid chromatography.Galloylpaeoniflorin is isolated and purified not have
Targetedly, its separation process is complicated, is unfavorable for the stabilization of galloylpaeoniflorin.
The content of the invention
It is contemplated that overcome prior art there is no a kind of extraction and purification process for galloylpaeoniflorin monomer, and
The isolated galloylpaeoniflorin monomer purity of existing method is low, and there is provided a kind of quick letter for the unstable defect of property
Just galloylpaeoniflorin monomer purity that is, with low cost, being applicable to industrialization production and obtain is high, property is stable does not eat
The preparation method of sub- acyl Paeoniflorin monomer.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions：
A kind of preparation method of galloylpaeoniflorin monomer, comprises the steps：
A, extraction：
Radix paeoniae rubrathe dry root is ground into coarse powder, the ethanol solution that mass percent concentration is 65%~75% is added, refluxing extraction is carried
Take liquid to filter, remove ethanol, obtain the equivalent extract that the relative density at 45 DEG C~50 DEG C is 1.30-1.40；
B, extraction：
Equivalent extract obtained by step A is first added into water to be disperseed, dispersion soln is obtained, petroleum ether extraction is then added, stone is removed
Oily ether extract, aqueous phase adds ethyl acetate extraction, collects acetic acid ethyl acetate extract, is concentrated to dryness, obtains infanticide acyl Paeoniflorin thick
Product；
C, preparation：
By galloylpaeoniflorin crude product:Methanol=1g:3ml ratio, the galloylpaeoniflorin crude product that step B is obtained is used
Methanol is completely dissolved, dissolving completely after uses nanometer organic membrane filter, filtrate again through C18 reverse-phase chromatography filler high pressure preparative separations,
Corresponding chromatographic peak is collected, methanol is reclaimed, remaining aqueous solution adds ethyl acetate to extract, gained ethyl acetate extraction liquid is collected, plus
Enter after anhydrous sodium sulfate dehydration, being concentrated under reduced pressure into no ethyl acetate under the conditions of 40 DEG C~45 DEG C obtains white solid, white solid
Galloylpaeoniflorin monomer product is can obtain after being dried under reduced pressure under the conditions of 45 DEG C.C18 reverse-phase chromatographies in the step are filled out
It is 4~5MPa to expect the high pressure in high pressure preparative separation.
In step, 10~15L of ethanol is added per the 1Kg radix paeoniae rubrathe.
In stepb, when adding water scattered, the volume that water is added is 10~15 times of equivalent extract volume.
In stepb, plus during petroleum ether extraction, each addition is 2~3 times of dispersion soln volume, and aqueous phase adds second
When acetoacetic ester is extracted, the consumption of each ethyl acetate is 2~3 times of the aqueous phase volume.
In step C, the aperture of the nanometer organic membrane filter is 220nm~450nm.
In step C, the mobile phase of the C18 reverse-phase chromatographies filler high pressure preparative separation presses 45 for first alcohol and water:55
The solvent of volume proportion；Detection wavelength is 220nm~230nm.
In step C, when remaining aqueous solution adds the ethyl acetate to extract, extraction every time adds the acetic acid second of 1~2 times of the aqueous solution
Ester.
The pressure for being concentrated under reduced pressure, being dried under reduced pressure in above-mentioned steps can be -0.1MPa.
The invention has the advantages that：
The specific ethyl acetate of equivalent extract that the present invention extracts the radix paeoniae rubrathe extracts, methanol dissolves, nanometer organic membrane filter, and filtrate passes through again
C18 reverse-phase chromatography filler high pressure preparative separations, prepare the galloylpaeoniflorin monomer product of purity >=98%.Whole work
It is skill process operation simplicity, process stabilizing, with low cost, and separative efficiency is high, product purity is high, is adapted to industrialized production high-purity
Galloylpaeoniflorin monomer.
The present invention is studied by long-term experiment, only need to be by ethyl acetate extraction, methanol dissolving, nanometer organic membrane filter, filter
Liquid prepares these steps with regard to that can obtain through C18 reverse-phase chromatography filler high pressures again, the galloylpaeoniflorin monomer of purity >=98%
Product, it is to avoid prior art preparation process in galloylpaeoniflorin monomer is long, nutgall caused by operating procedure is numerous and diverse
The problem of acyl Paeoniflorin monomer stability is poor.
The present invention uses nanometer organic membrane filter after obtained galloylpaeoniflorin crude product methanol is dissolved, it is ensured that high pressure
Pressure prepared by liquid phase is normally run in 4-5MPa working environment.
