title: Structural studies on minor components of saframycin group antibiotics saframycins F, G and H.
abstract: Three minor components of saframycin group antibiotics, saframycins F, G and H were isolated and their structures were determined by comparison with the spectral data of UV, IR, and 1H and 13C NMR of already reported saframycins A and D. Saframycins F, G and H were 21-cyanosaframycin D, 14-hydroxysaframycin A and 25-dihydro-25-beta-ketopropyl-saframycin A, respectively.
