ABSTRACT
The fresh rhizomes of the four varieties of turmeric (Curcuma longa) viz., IISR Alleppy Supreme, BSR-2, Rasmi and Narendra Haldi-1 were collected from 7-8 month old plants that were grown in the experimental plot in the orchard, Department of Spices and Plantation crops, TNAU, Coimbatore and the essential oils of each varieties were obtained by hydrodistillation. The volatile compounds present in the oil were analysed by GC-MS. Thirty four components were detected of which the major volatile compounds obtained were Ar-tumerone, ?-tumerone and ?-tumerone. The composition of the volatile compounds varied with respect to varieties. Ar-tumerone was high in Rasmi (52.96%) while it was low in Narendra Haldi-1(45.65%). ?-tumerone was high in Narendra Haldi-1 (24.78%) and low in IISR Alleppy Supreme (21%). The same trend was seen in the case of ?-tumerone. Zingiberene content in BSR-2 was 5.05%, whereas in IISR Alleppy Supreme, the content was 1.55% and a negligible amount was found in Rasmi.
Key words :
?-tumerone, Ar-tumerone, ?-tumerone, Curcuma longa, essential oils, turmeric.
