Amino sugars mass spectra

Holacurtinol (40) is a minor alkaloid. The mass-spectrum showed fragments attributable to successive losses of two molecules of HjO suggesting the presence of two hydroxyl groups. The NMR spectral data showed the presence of the same sugar unit (4-deoxy-4-amino-P-D-cymaropyranose) as in 37 and 39, while the pregnane aglycone portion was similar to that of... [Pg.324]

Mass spectrometry is also applicable to the study of macrolide antibiotics containing amino sugars. The mass spectrum of the antibiotic... [Pg.215]
