The invention relates to a compound menstruum for extracting tylosin and an extraction method. According to the invention, the compound menstruum formed by mixing butyl acetate, isobutyl acetate and butanol according to the volume ratio of 6:3 to 3.2 to 0.8-1 is used for extracting tylosin in fermentation filtrate through a secondary counter-current extraction method. The method has the advantages of low consumption of organic menstruum, low loss of tylosin, short extraction time, high extraction yield and the like. |
