Problems solved by technology

[0008] Although the above-mentioned resin adsorption method has been relatively fully approved in specific industrial production, it also has the following defects: the resins used in the first current resin adsorption method are mostly non-polar macroporous adsorption resins, which are not suitable for the alternative The control of the proportion of each component of lanin has a great influence, and the effect of decolorization and impurity removal is not ideal; the second is the final precipitation operation, usually by adding acetone to a concentration of 90% acetone to separate out teicoplanin, which requires a large amount of acetone, greatly aggravating the pressure of environmental protection, and affecting the production environment and personnel health

Abstract

The invention provides a teicoplanin purifying method. The purifying method includes steps of orderly performing resin gathering, resin purification, film concentration, and spraying drying operations on teicoplanin fermentation liquor. Compared with the prior art, polarity macroporous adsorbing rein is combined with a medium-sized polarity chromatography resin with uniform grain diameter, thus the product yield is high and decoloring effect is good; the spraying drying technology avoids the massive use of acetone, so that environment is protected, cost is reduced and problem of residue of organic solvent in the prior art can be further avoided; the ratio of every component of the teicoplanin obtained through the purifying method can meet standard, the purifying process is high-efficient and convenient, the preparation amount is big; the teicoplanin purifying method is applicable to industrial production.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of pharmaceutical engineering, in particular to a method for purifying teicoplanin. [0003] 【Background technique】 [0004] Teicoplanin (teicoplanin) is another glycopeptide antibiotic developed after vancomycin against drug-resistant bacteria. In the existing teicoplanin production method, generally adopt microbial fermentation to produce teicoplanin as main, and the teicoplanin in the fermented liquid comprises TAl~TA2, and wherein TA2 is the main active ingredient of teicoplanin, mainly consists of 5 It consists of two compounds (TA2-1, TA2-2, TA2-3, TA2-4, TA2-5) with very similar chemical structures; its crude and refined products also contain an active component TA3-1, which is TA2 The deacylated glucosamine product; in addition, it also contains 2 analogs with strong lipophilicity. The chemical structure of teicoplanin is shown in Formula 1 below. At present, among the standards followed in the phar...
