Abstract

A process for extracting natural flavonoid and/or terpene lactones from plant by adsorbent includes such steps as extracting the plant containing flavonoid and/or terpene lactones matter in alcohol to obtain aqueous solution, loading it in resin column containing urea-form aldehyde type adsorptive resin,washing, desorptin, concentrating, drying and pulverizing. The powdered extract contains flavone glycoside (24-42%) and terpene lactone (6-15%), or contains flavone glycoside (more than 62%). Its advantages are one-step desorption, simple process, low cost and high quality of product.

Description

From plant, extract the method for natural flavonoid and/or terpene lactones with sorbent material
The invention belongs to the selection adsorption separating method of sorbent treatment liquid.
The skeleton overwhelming majority of common polymeric adsorbent is crosslinked polystyrene or poly-(methyl) acrylate, surface modification can improve resin to some organic adsorption selectivity, but because the existence of hydrophobic framework, selectivity is difficult to further improve, this has limited polymeric adsorbent at water-soluble (or strongly hydrophilic) natural product, as the extraction of flavones and glucoside thereof with separate in widespread use.Though some early stage patents have been reported the synthetic of urea aldehyde type polymeric adsorbent and in fruit wine the application aspect the selective removal of phenolic substance (Ger.Offen 2437640; Ger.Offen 2521689; Ger.Offen 2437629), but these resins all are the powder of polycondensate through grinding of urea and formaldehyde, generally all can not carry out column operation when practical application.(US 4010242 for the precipitation polymerization method synthetic method of reporting in the at present existing document of having only the micron level spherical urea-formaldehyde resin; J.Chromatogr.1989,476:21), its step is polycondensation in silicon sol with urea and formaldehyde, the embedding of aftercondensated thing has been finished in polymerization silica particle, from water, be precipitated out and obtain the coacervate matrix, handle removal silicon-dioxide with Ammonium bi-fluoride then and promptly get required resin, particle diameter is between 5~10 microns, can be used as chromatograph packing material, but do not see the bibliographical information of the extraction and purification that urea aldehyde type resin is used for plant milk extracts such as Ginkgo Leaf (content of standard extract flavonoid glycoside and terpene lactones must respectively more than or equal to 24% and 6%) so far as yet, has only D-101 at present, Duolite S-761, the report that polymeric adsorbent such as HP-20 and XAD-7 is used in this respect (Chinese Journal of Pharmaceuticals, 1990,21 (8): 340; The flat 2-121998 of JP; The flat 3-98592 of JP; The flat 3-914900 of JP), qualified Folium Ginkgo extract to be obtained, the method for stepwise elution must be adopted with these polymeric adsorbents, complex process not only, the cost height, and also flavonoid glycoside and two kinds of compositions of terpene lactones all have greater loss.
The purpose of this invention is to provide the spherical urea aldehyde of a kind of usefulness type polymeric adsorbent extracts flavonoid and/or terpene lactones material from plant method, this method is an one-step elution, and technology is simple, cost is low, the loss of flavonoid glycoside and two kinds of compositions of terpene lactones is less, quality product improves.The Stability Analysis of Structures of this spherical urea aldehyde type polymeric adsorbent, flavonoid and terpene lactones material all there is very high selectivity.
The object of the present invention is achieved like this: pack urea aldehyde type polymeric adsorbent (sorbent material) into post directly for 20mm~1m, the resin volume is 50ml~1m 3Post in device resin post; The plant that will contain Flavonoid substances and/or terpene lactones material is pulverized, carrying out ethanol percolation or aqueous ethanolic solution heat extracts, after extracting solution reclaims ethanol, dilute with water, filter clear aqueous solution, the aqueous solution that obtains is fed in the above-mentioned resin column, wherein flavones ingredient and terpene lactones composition are adsorbed in the resin effectively, after washing, use 70% alcohol desorption again, absorption, washing, the flow velocity of desorb be 0.5~2 times of resin bed volume/hour, stripping liquid is through concentrating under reduced pressure, dry, pulverizing and promptly getting Powdered active constituent content is flavonoid glycoside 24%~42% (w/w) and terpene lactones 6%~15% (w/w), or flavonoid glycoside is the extract more than 62%.
Above-mentioned urea aldehyde type polymeric adsorbent is in order to operation preparation down, at normal temperatures with 38~50% (w/w) urea, the concentration of 62%~50% (w/w) is the organic bases of 36~38% (w%) formalins and 0.5%~1% (w/w), as diethylenetriamine, or triethylene tetramine, or tetraethylene pentamine, mix, after treating urea dissolving fully, hydrochloric acid with 5% is transferred pH=7~8, begin then to heat up, slowly be warming up to 92~95 ℃ in one hour, and this temperature continuation reaction 2 hours, get the simple linear polymer aqueous solution (I), in (I), be incorporated as the organic compound of the water-soluble hydroxyl of (I) weight 10~45% (w%), as ethanol, or ethylene glycol, or glycerine, or glucose, or water soluble starch, add 1% (w%) concentrated hydrochloric acid again, mixing, get the aqueous solution (II), with 0.3~0.7% (w/w) nonionic surfactant, as the class of department, or soil temperature, or their mixture, being dissolved in its volume is 2~4 times organic solvent of water, cured as liquid, or chlorobenzene, or orthodichlorobenzene, or in their mixture, under agitation add the aqueous solution (II) then, be warming up to 30~45 ℃ of reactions more than 3 hours, after filtration, aftertreatments such as washing, preparing granularity is the spherical urea aldehyde type polymeric adsorbent of 0.3~0.8mm, and its granularity is 0.3~0.8mm.
The main equation of whole building-up reactions can be expressed as follows:
1) simple linear polymer is synthetic
Figure A9910034700041
2) the synthetic spherical resin of inverse suspension polymerization method
Used plant is when containing the Ginkgo Leaf of flavonoid glycoside and terpene lactones, and containing flavonoid glycoside in the final Powdered extract of gained is that 24%~42% (w/w) and terpene lactones are 6%~15% (w/w); Used plant is when containing the Howthorn Leaf of flavonoid glycoside, and containing flavonoid glycoside in the final Powdered extract of gained is 62.4% (w/w).
The present invention compared with prior art, the advantage that has is: the novel polymeric adsorbent that makes with synthetic method of the present invention is the smooth, spherical of Φ=0.3-0.8mm, and contains a large amount of wetting ability hydroxyls, steady chemical structure, skeletal density is up to 1.61g/cm 3, the specific surface area of dried resin is at 50~120m 2Between/the g, flavonoid and terpene lactones natural product all had very high adsorption selectivity, Static Adsorption amount to flavonoid glycoside in the Ginkgo Leaf is the 45.6mg/g dried resin, Static Adsorption amount to Folium Ginkgo terpene lactones is the 31mg/g dried resin, to other herbal medicine or plant, all show good selectivity as the flavonoids effective constituent in Howthorn Leaf etc.Extract purifying flavonoid and terpene lactones with this resinoid, need only carry out the extract that one-step elution just can obtain being higher than international medicine or foodstuff additive requirement.In addition, this resinoid is when all kinds of SOLVENTS replaces, and swelling capacity changes less, is respectively 11.0,11.0,10.0,10.0 and 9.7 milliliters as the volume of 5 gram dried resins in water, ethanol, acetone, sherwood oil and normal heptane, is convenient to carry out column operation.Compare with other resin, the present invention is owing to adopted the method for a step desorb, and the loss of flavonoid glycoside reduces to and is not more than 3% (stepwise elution about 10%), and the loss of terpene lactones reduces to and is not more than 1% (stepwise elution about 30%).Raw materials used cheap of production resin of the present invention.
