Separation and preparation of isovaleryl-spiramycin II |
| abstract |
The invention relates to the separation of antibiotic and the application of the antibiotic in resisting infectious diseases, in particular to an isovaleryl-spiramycin II single-component compound. A kelimycin sample is separated by HPLC (high performance liquid chromatography) after crude separation, high-efficiency purification and post-processing, so as to obtain the pure isovaleryl-spiramycin II compound. Biological experiment results show that the antibacterial activity of the isovaleryl-spiramycin II compound is better than that of kelimycin and is much better than that of a control group. The invention lays the foundation for developing the clinical and effective isovaleryl-spiramycin II single-component antibiotic. |
