【Abstract】 Meilingmycin was separated and purified by taking the advantage of the different properties of nanchangmycin and meilingmycin. The former degraded when heating at low pH condition while the latter kept intact. The impurities formed after treatment were removed by solvent extraction. On the basis of results of the full wave scanning, HPLC determination and mass spectrum analysis, the molecular formulas of meilingmycin homologues had been proposed.更多还原
