Studies on the Essential Oils of Tobacco Leaves

Part XIII. Basic Fraction (1)

Abstract

The basic fraction contained in the essential oil of the Japanese Flue Cured Tobacco Leaf (before redrying) was investigated and 2, 3'-dipyridyl was isolated and identified. While, on the other hand, the basic fraction of the essential oil of the aged Japanese Burley Tobacco Leaf was also investigated and nicotine was found to be the predominant constituent of that fraction. At the same time, a small amount of 2, 3'-dipyridyl and myosmine was also iso-lated and identified.
