title: [Ultra-violet spectrophotometry in drug control. Part 23: Conclusions from the spectrophotometric behaviour of drugs with pyridine, naphthalene, quinoline and isoquinoline chromophores (author's transl)].
abstract: The results from a systematic study of drugs with pyridine, naphthalene, quinoline and isoquinoline chromophores are evaluated and condensed into conclusions. In addition to previously reported findings, the ultra-violet and visible spectra of a further nine drugs containing the mentioned chromophores are presented.
