Structural elucidation of A6'7-anhydroerythromycin D using H-NMR-spectrometer
1-1-NMR-spectrometric analysis was carried out to samples I and 2 which were isolated respectively from Saccharopolyspora erythraea ATCC 11912 with and without additional isonicotinic hydrzide (INH). The sample I was confirmed as erythromycin D due to the proton appearance of 12-H at 32.3175 (dq) of...

| 總結: | 1-1-NMR-spectrometric analysis was carried out to samples I and 2 which were isolated respectively from Saccharopolyspora erythraea ATCC 11912 with and without additional isonicotinic hydrzide (INH). The sample I was confirmed as erythromycin D due to the proton appearance of 12-H at 32.3175 (dq) of the macrolactone, and the absence of 3"-niethoxy proton at 3.31 (s) of its neutral sugar. The sample 2 was confirmed as 46'7-anhydroerythromycin D due to the presence of 7-H(-C=C-) at 35.343 (dq) instead of the methylene proton at C, |
