| titleOfInvention | High purity lipiarmycin A4 preparation method |
| abstract | The invention discloses a high purity lipiarmycin A4 preparation method which comprises the following steps: A, filtering lipiarmycin A4 fermentation broth to obtain mycelium, soaking the mycelium with a polar solvent for solid-liquid separation to obtain lipiarmycin A4 extracting solution; B, concentrating the lipiarmycin A4 extracting solution, extracting the lipiarmycin A4 extracting solution with ethyl acetate, concentrating and drying the extracting solution to obtain lipiarmycin A4 coarse powder; C, dissolving the lipiarmycin A4 coarse powder in an organic solvent, filtering with a 0.45 mum filter membrane to obtain a sample loading solution; and D, adding the sample loading solution into a medium pressure chromatography column filled with C18, adding an elution solvent, collecting eluant with the content greater than or equal to 98.5% by high performance liquid chromatography, concentrating, filtering and drying in vacuum to obtain a high purity lipiarmycin A4 product. The high purity lipiarmycin A4 preparation method has the advantages of simple operation, high sample recovery rate, and suitability for high purity antagonizing drug-resistance antibiotic production. |
