Abstract
A trace amount of nicotine, main constituent in tobacco, contaminated in coffee, was identified by the T.L.C method. The Eastman chromagram plate was used and determined with the linear scanning by transmission method. It was possible to identify nicotine in coffee beverage regardless of types of tobacco. Ten micrograms of nicotine could be determined in a cup of coffee (75ml), which was acidified with hydrochloric acid.
