Abstract: | Free amino acids in the cigarette smoke, produced in constant-volume continuous smoking by the use of an artificial smoking-device, have been paper-chromatographically studied, and twelve amino acids, i.e., α-alanine, β-alanine, glycine, glutamic acid, glutamine, serine, γ-amino butyric acid, valine, leucine, aspartic acid, proline, and ornithine(?) were qualitatively identified. Besides these amino acids, the presence of the other two unidentified ninhydrin-positive substances was observed. The presence of ten amino acids, other than glutamic acid and glutamine, has not yet been reported in the literature concerning tobacco smoke. |
