    摘要： The invention relates to derivatives of 12,13-epoxy-tylosin, the novel seynthetic antibiotics from tylosin group and the methods of their preparation. According to this invention hydrogenation followed by oximation of 12,13-epoxy-tylosin derivatives yields the following tylosin derivatives: 10,11-dihydro-12,13-epoxy, respectively 10,11-dihydro-12,13-epoxy oxime. Direct oximation of 12,13-epoxy tylosin derivative gives 12,13-epoxy oxime derivatives of tylosin.
