An investigation was conducted on the neutral fraction in the essential oil of Virginia tobacco leaves. α-Pyrryl methyl ketone, ethyl alcohol, ethyl acetate and furfuryl alcohol were isolated and identified. An alcohol, C4, and an ester of benzoic acid were also separated. Hydrocarbons were separated from the total neutral fraction by liquid chromatography, prior to any further procedure; and a straight chain paraffin near C30 and an unsaturated hydro-carbon resembling myrcene were also isolated and their contents were determined. A technique of chromatostrip was found to be very useful for detecting liquid chromatographic separation.
