Chemical Composition of Curcuma Longa Leaves and Rhizome Oil from the Plains of Northern India

Hydro distillation of rhizomes and leaves of Curcuma longa resulted in the isolation of 0.36% and 0.53% of oils (w/v) respectively on a fresh weight basis. GC and GC-MS analysis resulted in the identification of 73 constituents in rhizomes comprising 95.2% of the oil, of which the major ones were ar-turmerone (31.7%), alpha-turmerone (12.9%), beta-turmerone (12.0%) and (Z) beta-ocimene (5.5%). In the oils, 75 constituents comprising 77.5% of the oils were identified, the major ones were alpha-phellantrene (9.1%), terpinolene (8.8%), 1,8-cinceole (7.3%), undecanol (7.1) and p-cymene (5.5%).
