Description
Technical field
The present invention relates to a kind of preparation method of acarbose, especially relate to a kind of method of utilizing membrane technique to prepare high-purity acarbose.
Background technology
Acarbose (Acarbose) is a kind of a-heteroside enzyme inhibitors, and molecular weight is 650, can be used as the antidiabetic medicine of oral administration type ii diabetes, and trade(brand)name is Bay g 5421.This active compound is to produce by fermentation, and producing bacterial classification is soil microorganisms actinoplanes SE50/110 or its mutant of deriving, and acarbose must be separated from meat soup after fermentation produces, and makes pure product.
Acarbose active compound content in fermenting broth is not high, about 1500 mcg/ml, and purification technique all is to adopt the ion exchange resin of different structures that acarbose is adsorbed purification at present.For this reason, No. 2347782, German patent specification, No. 2719912 and No. 86108259 grades of Chinese patent specification sheets all have description.Germany Bayer AG discloses a kind of preparation method of highly purified acarbose in Chinese patent 86108259 specification sheetss, wherein contain the carbohydrate submember that was less than for 10% (by weight), it is that to separate PH by column chromatography be that the pre-acarbose solution of purifying of process of 4-7 makes.This method is a kind of of gel extraction method.Wherein chromatographic column contains the weak-type cationite as packing material, described exchanger tool carboxyl functional group, and be matrix with dextran, agarose and Mierocrystalline cellulose, exchanger or derived and got by the above-mentioned substance that has added polymeric amide.The content of the acarbose after this method is purified is increased to and was at least for 90% (by weight), and the carbohydrate submember was less than for 10% (by weight).
Enterprise with domestic existing production acarbose all adopts above-mentioned ion exchange technique to purify to the purification of acarbose fermentation liquid in the world, the method that adopts is shown in Fig. 1 feel flow draw of block, be specially: with acarbose fermentation liquid, be warmed up to 90 ℃ of sterilizations, add flocculation agent flocculation back by Plate Filtration, collect acarbose filtrate; It is acid regulating pH value with hydrochloric acid, continuously by resin cation (R.C.) and resin anion(R.A) absorption part pigment and mineral ion; Then, carry out that vacuum and low temperature concentrates and resin anion(R.A) transfers pH value to neutral, and decolour, then by the macroporous resin adsorption acarbose, with concentrating behind dilute hydrochloric acid or the buffer solution elution acarbose, the pH value of regulating the acarbose concentrated solution with resin anion(R.A) is to neutral, re-use highly acidic resin absorption acarbose, separate wash-out acarbose and homologue, collect high-purity acarbose liquid, after the pH value of regulating acarbose solution with resin anion(R.A) is neutrality once more, concentrate, carry out spraying drying or cryodrying, make the acarbose finished product.
Shortcomings such as this method exists acarbose effective ingredient yield low in sepn process, and preparation method's cost is higher, labour intensity is big, energy consumption is big and the resin usage quantity is big, soda acid is seriously polluted.
Utilize membrane separation technique, nano level ultrafiltration membrane technique especially, being used for the cutting of molecular level separating substances is an isolation technique that develops rapidly in recent years.Select the film separating system of different qualities, under certain conditions, optionally the allied substances of certain molecular weight scope is held back, improve the purity of extract greatly.The companies such as Millpore, Osmonic of the Sumitomo Electric Industries of Japan, day eastern electrician, the U.S. have developed a series of separatory membranes and membrane sepn treatment system in succession, require technology to select for use for the various separating substances of industries such as medicine, biochemistry.
Summary of the invention
The inventive method adopts the nano-scale systems membrane separation technique, the binding resin absorbing process, acarbose is purified from the fermented liquid that contains remaining salt, coloring matter and other macromole impurity, improve the extraction yield and the purity of acarbose effective ingredient, thereby the use of minimizing resin has reduced the usage quantity of soda acid, reduces environmental pollution, reduce production costs, reduce investment outlay, reduce labor intensity, improve Working environment.
A kind of method for preparing high-purity acarbose is got acarbose fermentation liquid, after the intensification sterilization, by the primary membrane separation system, adopts membrane separation process to handle, and collects acarbose liquid; The acarbose liquid cooling back of collecting is passed through the resin cation (R.C.) desalination bleaching by the sour pH value of regulating to acid back, transfer pH value to neutral and decolouring, to enter the one-level film separating system by resin anion(R.A) again, adopt membrane separation process to handle, collect liquid and enter secondary film purifying concentration systems, purifying concentrates, and gets the acarbose concentrated solution; The acarbose concentrated solution passes through strongly-acid macroporous resin adsorption acarbose by resin anion(R.A) adjusting pH value to neutral back, and collection purity is the pure akakpo sugar solution more than 98% after the gradient pickling; Pure akakpo sugar solution enters three grades of film purifying concentration systems after by resin anion(R.A) pH value being adjusted to neutrality, and purifying concentrates, and obtains high-purity acarbose liquid; High-purity acarbose liquid carries out getting the high-purity acarbose finished product after the drying.
Described separating technology is: the pending liquid of acarbose (comprising acarbose fermentation liquid and acarbose liquid) is by the film system, after isolating 90% acarbose, the water that adds original volume 10% volume enters in the pending liquid, separate once more, after isolating remaining 50% acarbose, the water that adds original volume 10% again enters in the pending liquid, and repeated isolation reaches more than 95% acarbose membrane sepn yield.
The film of the employing of described film separating system is an inorganic material film, as ceramic membrane, clay membrane, metallic membrane.
The molecular weight cut-off of the film that described primary membrane separation system adopts is 100000 grades.
