(Japanese Patent Application No. 54-24788, Patent Application No. 31316-1983). The object compound [1] of the present invention includes two types of epimers and mixtures thereof depending on the coordination of the hydroxyl group at the 9-position. The above salts include pharmaceutically acceptable salts, such as salts with inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, propionic acid, tartaric acid, citric acid, succinic acid, malic acid, aspartic acid, glutamic acid, It is a salt with various organic acids such as sulfonic acids. Other non-toxic salts are also included. The above target compound [1] and its salts have antibacterial activity against Gram-positive bacteria, Gram-negative bacteria, and mycoplasma, and are not only antibacterial substances that are expected to have excellent clinical infection-curing effects, but also It is useful as a preventive and curing agent for diseases of the world, and is also useful as a feed additive. The object compound [1] of the present invention can be obtained by reducing mycinamicin with sodium borohydride in an inert organic solvent. As the inert organic solvent, lower alkanols such as methanol and ethanol are preferred. The reaction usually proceeds at room temperature. Since the reaction time can be monitored by thin layer chromatography using silica gel or the like, the reaction can be appropriately terminated after waiting for the disappearance of mycinamicin or the like. To collect the obtained compound [1] from the reaction solution, the reaction solution was poured into water, extracted with a non-hydrophilic organic solvent, and the obtained extract was washed with water and dried under reduced pressure. It is obtained by purification by column chromatography using an adsorbent such as alumina or adsorption resin. Next, Table 1 shows the results of measuring the antibacterial spectrum of the object compound [1] of the present invention.
