Description

The method of separating short-tube lycoris alkali from plant milk extract
(1) technical field
The present invention relates to the extracting method of the effective medicinal ingredients of plant, especially from the plant milk extract that contains amaryllidaceae alkaloid, with narcissine and the isolating method of other numerous alkaloids.
(2) background technology
Narcissine (lycorine) can suppress the anaerobic glycolysis of mouse ascites cancer cells, and mouse lymph sarcoma, sarcoma 37 and rat lymphosarcoma, liver cancer cell are had remarkable restraining effect; Hela cell, sarcoma 180, ehrlich carcinoma, ascites liver cancer and yoshida sarcoma also there is restraining effect.It also is the raw material of preparation cancer therapy drug oxylycorine (AT-1840).
Narcissine structural formula such as figure below.
Narcissine extracts from natural phant.These plants are distributed in fields such as Lycoris, Crinum, Narcissus, Haemanthus.Wherein representative with lycoris plants.The method of prior art separating short-tube lycoris alkali from plant milk extract mainly is an organic solvent extractionprocess.Utilize the lipotropy alkaloid to be dissolved in the lipotropy organic solvent, and the water-soluble character of its salt, and the difference of alkalescence between the various haplont alkali in the total alkaloids, under different pH conditions, separate.
Shortcoming and defect such as the technology of said extracted, separating short-tube lycoris alkali exists that organic solvent consumption is big, be easy to generate emulsion during extraction, influence the separation and Extraction effect, operative employee's duration.
Along with the continuous expansion of ion exchange resin Application Areas, the method for ion-exchange is also adopted in many alkaloidal separation.But above-mentioned patent documentation and non-patent literature there is no the identical record with the method for ion exchange resin absorption, wash-out narcissine of claim relevant and of the present invention.
(3) summary of the invention
Contain and contain tens of kinds of alkaloids such as narcissine, narcissine, narcissine in the amaryllidaceae alkaloid plant milk extract.The invention provides a kind of method by ion-exchange chromatography separating short-tube lycoris alkali, have that yield height, purity are good, an advantage of saving working hour, material saving.
Task of the present invention realizes by following technical scheme.
Contain the amaryllidaceae alkaloid plant milk extract through pre-treatment, according to used resin choice, with sample preparation is acid, neutral or alkaline, with Zeo-karb adsorb, wash-out, tracking detection wash-out stream part, enrichment method narcissine section stream part gets narcissine free alkali crude product, again with the organic solvent recrystallization, purity is about 99% narcissine free alkali crystallization.
The parent of described Zeo-karb is a kind of in SDEB styrene diethylenebenzene, resol, crosslinked polystyrene, the dextran.The functional group of Zeo-karb is a kind of formed strong acid in sulfonic group, methylsulphonic acid base, phosphate, carboxyl and the phenolic group, middle strong acid, weakly acidic cationic exchanger resin.The preferred cation exchange resin is a STREAMLINE SP resin.
Basic technology method of the present invention is as follows:
1. contain the pre-treatment of amaryllidaceae alkaloid plant milk extract: pretreated purpose is absorption or the exchange that helps the plant extract matter sample.Adopt different pretreatment processs according to the chromatographic technique that is adopted.Comprising, regulate the pH value that goes up sample solution with acid or alkali; By filtering or centrifugation method is removed solid particulate in the solution; And with sample through carrying out method such as chromatographic separation after the initial gross separation again.The acid that is used to regulate the pH value does not have specific limited, preferably hydrochloric acid or sulfuric acid, and concentration is 0.1%-10%; The alkali that is used to regulate the pH value does not have specific limited yet, preferably sodium hydroxide or ammoniacal liquor, and concentration is 1%-20%
2. the exchange of sample or absorption: ion exchange resin makes the transition, and is positioned over by any way in the exchange column, sample and ion exchange resin are adsorbed or exchanges.Absorption or exchange can be adopted dynamic method, also can adopt stationary method, and dynamic method preferably.
3. washing: be lower than the washing soln washing Zeo-karb of elute soln ionic strength to be higher than the equalizing and buffering solution ion strength, not combined thing under the wash-out from the Zeo-karb.The washing soln volume is 2-3 a times of column volume, and flow velocity is 2-3ml/min.
4. the wash-out of effective constituent: will adsorb or exchange the effective constituent material that gets on and discharge, and change people's elute soln again.Control elute soln volume, flow velocity 2-3ml/min.Type of elution can adopt dynamic desorption or static wash-out, but dynamic desorption mode preferably.Wash-out can adopt gradient elution or non-gradient elution.
Elute soln can be the salts solution bigger than the ionic strength of balanced solution, and for strengthening organic solvent that the ion elute effect takes as toughener.Preferred salt is sodium-chlor, and concentration is 0.1mol/L-10mol/L, and preferred toughener is an ethanol, and concentration is 10%-20%; Elute soln also can be the buffered soln bigger than balanced solution pH value; Elute soln can also be the mixing solutions of alkali and organic solvent, and preferred alkali is ammonia, and concentration is 1%-20%, and preferred organic is an ethanol, and concentration is 10%-95%.
5. the tracking of wash-out stream part detects and collects: when wash-out stream part, the tracking that should carry out the active substance narcissine detects.Detection method can be used thin-layer chromatography (TLC) method, also can use the method that other are suitable for detecting narcissine.According to detected result, collection, the identical R of merging with narcissine fStream part of value.
6. flow the enrichment method of narcissine in part: the narcissine in enrichment method wash-out stream part can adopt extraction and/or distill spissated method.
Usually through enrichment method, can obtain the crude product of narcissine free alkali.
7. recrystallization: can use any organic solvent commonly used that narcissine free alkali crude product is carried out recrystallization, preferred solvent is a methyl alcohol.Through recrystallization, obtain the crystallization of pure product narcissine free alkali.Its purity is (HPLC) about 99%.
The method according to this invention can obtain narcissine effectively from vegetable material, be a kind of preparation method of separating short-tube lycoris alkali from the plant milk extract that contains amaryllidaceae alkaloid who is suitable for suitability for industrialized production.Advantage such as have the yield height, purity is good, technological operation is simple, save man-hour, raw materials consumption is few.
