The polyphenols and amino acids of tobacco leaf

A study of two different sources of tobacco leaf shows that rutin and chlorogenic acid are probably the most abundant polyphenols present. Other polyphenols are present in smaller amounts but caffeic acid and tannins were not detected, while isoquercitrin may possibly be present in trace amounts. To...

Summary:A study of two different sources of tobacco leaf shows that rutin and chlorogenic acid are probably the most abundant polyphenols present. Other polyphenols are present in smaller amounts but caffeic acid and tannins were not detected, while isoquercitrin may possibly be present in trace amounts. Tobacco leaf juice was shown chromatographically to contain aspartic and glutamic acids, asparagine, glutamine, and other amino acids. γ-Aminobutyric acid is also present, and in relatively large amounts in one of the sources investigated. There were several unidentified spots on the chromatogram not corresponding with known amino acids or other substances reacting with ninhydrin.
