The classical methods of chromatographic identification of compounds were based
on calculation of retention indices by using different stationary phases. The aim
of the work was to differentiate essential oils extracted from different plant
species by identification of some of their major compounds. The method of
identification was based on the calculation of new retention indices of essential
oils compounds fractionated on a polar chromatographic column with temperature
programming system. Similar chromatograms have been obtained on the same column
for one plant family with two different temperature gradients allowing the rapid 
identification of essential oils of different species, sub-species or chemotypes 
of Citrus, Mentha and Thymus.
