Description
Technical field
The present invention relates to a kind of method that from the erythromycin raw material, prepares high purity Erythromycin A, berythromycin, Erythromycin C, particularly relate to a kind of method that adopts high speed adverse current chromatogram to prepare high purity Erythromycin A, berythromycin, Erythromycin C.
Background technology
Erythromycin (Erythromycin is called for short EM) is a kind of Macrolide Broad spectrum antibiotics.The present known six kinds of isomer that wherein have are respectively Erythromycin A, B, and C, D, E and F, A are main active ingredient.The physico-chemical property of berythromycin and Erythromycin C and antimicrobial spectrum are similar to Erythromycin A, but their anti-microbial activity generally has only 30%～60% of Erythromycin A.Therefore, the major part of using in the medical treatment at present is an Erythromycin A.
The sample of highly purified erythromycin component all has crucial meaning for the research work of various relevant erythromycin.
The similar performance of Erythromycin A and berythromycin, Erythromycin C, general separation means are difficult to it is separated.High speed adverse current chromatogram (High Speed Counter Current Chromatography, HSCCC) be a kind of efficient liquid liquid distribution chromatography isolation technique that need not the solid support thing of releasing in 1980, successfully apply to fields such as biological chemistry, biotechnology, medical science, pharmacy, natural product chemistry, organic synthesis, chemical industry, environment, agricultural, material with its high-recovery, high preparative capacibility and high accumulation ability.High-speed countercurrent chromatography is gentle and effectively separate and make it obtain using widely separating antibiotic field, is especially seeming very potential aspect the preparation microbiotic standard substance.
Adopting high speed adverse current chromatogram to separate in the research work of preparation erythromycin component, people such as Booth adopt high speed adverse current chromatogram at solvent systems to be: normal hexane: ethyl acetate: methyl alcohol: water=1.4:2.0:2.0:1.0, theoretical plate number is not higher than separates the preparation Erythromycin A under 1219 the situation, obtained purity at the Erythromycin A more than 97%

And have not yet to see the research report that adopts high speed adverse current chromatogram to separate preparation high purity berythromycin, C, domestic do not have highly purified berythromycin and Erythromycin C sample to provide as yet yet.
Summary of the invention
The purpose of this invention is to provide a kind of method that from the erythromycin raw material, prepares high purity Erythromycin A, berythromycin and Erythromycin C.Present method can prepare Erythromycin A, berythromycin and Erythromycin C at the same time or separately.
The present invention takes following technical scheme: a kind of method that adopts high speed adverse current chromatogram to prepare high purity Erythromycin A, berythromycin, Erythromycin C, comprise: the solvent system that constitutes stationary phase, moving phase by normal hexane, ethyl acetate, methyl alcohol, water preparation, on be stationary phase mutually, be moving phase mutually down, make in the whole cylinder of counter current chromatograph to be full of stationary phase, again moving phase is pumped in the post; The erythromycin raw material that will contain erythromycin component A, B, C is dissolved in the following phase solvent, by the sampling valve sample introduction, uv atlas difference receiving target component Erythromycin A, berythromycin, Erythromycin C according to detector, and carry out lyophilize, it is characterized in that the consumption volume ratio of normal hexane, ethyl acetate, methyl alcohol, water is 0.5～1.3:0.5～2.0:0.5～2.0:1 in the described solvent system.
Wherein, said erythromycin raw material is the erythromycin that Yueyang produces with connection pharmaceutcal corporation, Ltd, and product batch number is 20060710.
In above-mentioned solvent system, when the consumption volume ratio of normal hexane, ethyl acetate, methyl alcohol, water was 0.6～1.2:1.0～2.0:0.8～1.6:1 in the described solvent system, the purity of the Erythromycin A that obtains was up to 90%～100%;
When the consumption volume ratio of normal hexane, ethyl acetate, methyl alcohol, water was 0.6～1.2:0.8～2.0:0.8～1.6:1 in the described solvent system, the purity of the berythromycin that obtains was up to 80%～100%;
When the consumption volume ratio of normal hexane, ethyl acetate, methyl alcohol, water was 0.6～1.2:1.0～2.0:0.8～1.2:1 in the described solvent system, the purity of the Erythromycin C that obtains was up to 70%～95%.
The invention has the advantages that: 1. adopted the high speed adverse current chromatogram separation method in present method, high-speed countercurrent chromatography has been avoided the chemical modification because of the sample loss that adsorption causes, sample component, separation efficiency can be compared with preparation HPLC with capacity, and does not generally have the conditions of streaking at peak.2. when under described solvent systems, adopting high speed adverse current chromatogram to separate preparation Erythromycin A, berythromycin, Erythromycin C in the method, can prepare Erythromycin A, berythromycin, Erythromycin C as required at the same time or separately; 3, present method is separated preparation Erythromycin A, berythromycin, Erythromycin C, number of effective theoretical plates be 1300～2500, have separate efficient, fast, fractional dose big, sample free of losses, rate of recovery height, isolating environment gentleness, save characteristics such as solvent.
