Abstract

A method for extracting tylosin by tylosin fermentation broth is characterized by including steps of firstly pretreating the tylosin fermentation broth to obtain tylosin filtrate, then subjecting the tylosin filtrate to extracting, reextracting, decolorizing filtering, crystallizing, ageing, rinsing and vacuum drying to obtain the tylosin. The method is used for directly extracting the tylosin by the tylosin fermentation broth serving as raw materials, tylosin solubility of intermediates of the tylosin accords with quality standards of Chinese Veterinary Pharmacopoeia. The integral method is mild in production conditions, simple to operate, safe and reliable in preparation process and low in loss of organic solvent and has the advantages of energy conservation, consumption reduction, low production cost, high work efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of biomedicine extraction, in particular to a method for extracting tylosine from tylosin fermentation liquid. Background technique [0002] Tylosine, also known as Tylosin and Tylosin, is a macrolide antibiotic obtained in the United States in 1959 from the culture medium of Streptomyces freundii. Tylosine is a white plate-like crystal, insoluble in water and alkaline. The products include tartrate, phosphate, hydrochloride, sulfate and lactate, which are easily soluble in water. [0003] As an intermediate of tylosin series products, tylosine plays a very important role. Tylosine raw materials at home and abroad are mainly used in three aspects, one is to make the raw materials into injections after aseptic treatment; one is to make them into salt antibiotic products as downstream products; the other is to use them directly Tylosine raw materials synthesize tilmicosin through a series of chemical reacti...
