Abstract
The invention relates to a process for co-producing total saponins and polysaccharide from star-of-Bethlehem, which comprises the following process steps: grinding the star-of-Bethlehem used as the raw material; carrying out reflux extraction for 2 to 3 times by using water; settling impurities by using a ZTC-II settling agent; enriching saponins and separating the polysaccharide by using macroporous resin; carrying out gradient alcohol precipitation repeatedly; carrying out decoloration by using an activated-charcoal column to prepare the polysaccharide; and adding a medium-pressure magnesia column and carrying out ethanol dissolution recrystallization to prepare the total saponins. By adopting the process, the content of the total saponins produced reaches 90 percent and the content of the polysaccharide reaches about 80 percent. The process has high raw material utilization rate.
Description
Technical field:
The invention belongs to the bioseparation technology field, the joint production process of particularly a kind of Herba Phyllanthi Urinariae's total saponins, polysaccharide.
Background technology:
Tiger eye Herba Phyllanthi Urinariae (Ornithogalum caudatum Ait) has another name called Rhizoma Picrorhizae Herba Phyllanthi Urinariae, Urginea maritima, calabash orchid, for Liliaceae tiger eye Herba Phyllanthi Urinariae, belongs to evergreen perennial bulbous plant, originates in the south, Africa.In northern China cultivation being arranged. among the people being used as medicine with herb or bulb, be mainly used in antiinflammatory and anticancer.Tiger eye Herba Phyllanthi Urinariae has high medical value, pharmaceutical research shows that the tiger eye Herba Phyllanthi Urinariae saponin OSW21 among the tiger eye Herba Phyllanthi Urinariae has tangible active anticancer to pulmonary carcinoma, breast carcinoma, external anti-p338 Lymphocytic leukemia is active result show, OSW21 is common cancer therapy drug camptothecine, Ah mould's rope, paclitaxel active anticancer 10～100 times, and normal cell there is not toxicity, therefore, be a kind of Chinese herbal medicine of great exploitation potential for its.
Mostly existing extraction separation Herba Phyllanthi Urinariae saponin technology is the old technology of tradition.Be that the lixiviate of Herba Phyllanthi Urinariae's leaf water temperature is got, the lead acetate precipitated impurities, activated carbon adsorption, ethanol extracts once more, thick glycosides water dissolution, with Carbon bisulfide, ether washing, chloroform extracts again successively, and the extraction of reuse chloroform alcohol water miscible fluid separates with alumina column, recrystallization obtains three kinds of monomer components, complex process is loaded down with trivial details, and reagent type is various, brings difficulty to recovery.Also have and utilize macroporous resin adsorption prepared saponin, " separation and Extraction of tiger eye Herba Phyllanthi Urinariae saponin " delivered as Xiao Chong etc. adopts ethanol extraction, defat with petroleum ether, AB-8 resin absorption, D-280 resin decolorization.The method of existing patent disclosure is also mostly to be preparations of crude extract, and as patent 200510069273 " Preparation method and use of tiger eye extracting active ingredient of starofbethlehem ", this method adopts ethanol extraction, and resin isolation obtains crude extract.
Existing disclosed Omithogalum caudatum polysaccharide technology, extracting method is simple, product content is lower, as patent 200510017123 " the tiger eye Omithogalum caudatum polysaccharide medicine of treatment hepatocarcinoma ", the method of this patent disclosure is that water is carried, and low alcohol precipitation precipitate discards, high again alcohol precipitation polysaccharide, washing with alcohol gets final product, polyoses content 50%.
Summary of the invention:
The technical problem to be solved in the present invention provides the joint production process of a kind of Herba Phyllanthi Urinariae's total saponins, polysaccharide, and this technology is fit to the separation of Herba Phyllanthi Urinariae's plurality of active ingredients, can improve Herba Phyllanthi Urinariae's utilization ratio of raw materials.
The object of the present invention is achieved like this:
The joint production process of a kind of Herba Phyllanthi Urinariae's total saponins, polysaccharide is characterized in that comprising following step:
1) extract: get Herba Phyllanthi Urinariae's pulverizing medicinal materials, added 5-8 times of water gaging reflux, extract, 1-2 hour, extract 2-3 time, merge extractive liquid, adds the clarifier sedimentation and filtration, collects filtrate;
2) macroporous resin adsorption: above-mentioned filtrate is added macroporous resin adsorption, collect lower column liquid, water-pure gradient elution is collected alcohol eluen;
3) alcohol eluen total saponins purification: with step 2) concentrates small size, adds compression leg in the magnesium oxide, the ethyl acetate-ethanol gradient elution is collected the saponin flow point and is concentrated small size, adds the ether precipitating, the precipitating thing leaches dissolve with ethanol crystallization 2-3 time, is drying to obtain Herba Phyllanthi Urinariae's total saponins;
4) polysaccharide purification: with step 2) lower column liquid is evaporated to density 1.1-1.3, adds ethanol gradient precipitate with ethanol, leaches the precipitate hot water dissolving, the polysaccharide activated carbon column decoloring, destaining solution concentrates and adds the ethanol precipitating, leaches precipitate, and low-temperature vacuum drying promptly gets Omithogalum caudatum polysaccharide.
Clarifier is the ZTC-II clarifier in the step 1), consumption 1-3 ‰.
Step 2) a kind of among the optional D101 of macroporous resin, AB-8 and the HZ816.Preferred HZ816.
Step 2) water-pure gradient elution is that 6-8 times of column volume washed 5-6 times of column volume 50-70% ethanol elution again in.
The ethyl acetate-ethanol gradient elution is 8-10 times of column volume eluent ethyl acetate 4-8 times of column volume 50-90% ethanol elution again in the step 3).Preferred 85% ethanol.
Crystallization condition is in the step 3): the 90-99% alcohol reflux dissolves, and is recycled to the 1/2-1/3 of original volume, leaves standstill crystallization.
Gradient precipitate with ethanol in the step 4) is three gradients of final concentration of alcohol 90%-70%-50%.
In sum, there is following advantage in the present invention: water refluxes to carry and helps the stripping simultaneously of saponin polysaccharide, and sedimentation agent can be removed macromolecular substances and part tannin, has improved the macroporous resin life-span; The compression leg processing speed is fast, effective in the magnesium oxide, total saponin content is high; Gradient precipitate with ethanol and activated-charcoal column purified polysaccharide, the polyose quality better.
