The present investigation was carried out to study the comparison of aroma constituents of two cultivars of tuberose (Polianthes tuberosa Linn.) flowers viz. Single petalled cv. Shringar and Double petalled cv. Vaibhav. It has been found that flowers of Single petalled cultivars gave characteristic aroma of tuberose which is further confirmed by Gas Chromatography (GC) profile of tuberose absolute. Attempts were therefore made to extract the concrete and absolute from the two cultivars of one each Single and Double types of tuberose. Gas chromatographic analysis showed the presence of Methyl iso-eugenol (40.37%) and Indole (1.88%) as major constituents in the absolute obtained from the cultivar of Single petalled florets Shringar, whereas Methyl Palmitate (24.46%) was found to be the major component in the absolute extracted from Double petalled florets of cultivar Vaibhav.
