Chemical composition of the ether and ethyl acetate extracts of Serbian selected tobacco types:: Yaka, Prilep and Otlja

A study of the chemical composition of ether and ethyl acetate extracts of the Serbian selected tobacco types Yaka, Prilep and Otlja was performed using GC and GUMS. The major constituents were: nicotine (24.2-58.9% of the total material detected in the ethyl acetate extracts and 46.1-49.5% of ether extracts), neophytadiene (4.0-17.9% of ethyl acetate extracts and 11.2-31.9% of ether extracts) and a mixture of n-, iso- and anteiso-alkanes (17.1-60.4% of ethyl acetate extracts and 8.4-24.7% of ether extracts). A detailed comparison of the obtained results with the composition of essential oils and supercritical CO2 extracts of the same tobacco types is presented.
