Chemical composition of leaf and rhizome oil of an elite genotype Curcuma longa L. from south eastern ghats of Orissa.

The present study reports the extraction of essential oil from leaf and rhizome of a commercially important cultivar of Curcuma longa L. (cv. Suroma) of south eastern ghat of Orissa using hydro-distillation and identification of its constituents through gas chromatography and mass spectrometry (GC-MS). The essential oil from fresh rhizomes showed ar-tumerone (49.76%) as a principal constituent. However, essential oil from leaf showed alpha-phellandrene (57.8%) as a major constituent.
