Chemical Constituents of Leaf Essential Oil of Curcuma angustifolia Roxb. Growing in Eastern India

Curcuma angustifolia Roxb. (Family: Zingiberaceae) is an important rhizomatous medicinal herb, grows wild in India. The leaf essential oil of C. angustifolia was extracted by hydro-distillation and analyzed by using Gas chromatography/Mass spectrometry (GC-MS). Forty six compounds comprising 91.17 % of the total peak area were identified. The major components of the leaf essential oil were 8,9-dehydro-9-formyl-cycloisolongifolene (33.48 %) followed by curzerenone (11.81 %), xanthorrhizol isomer (7.59 %), eucalyptol (6.62 %), camphor (3.27 %), germacrone (3.21 %), xanthorrhizol (2.98 %), ar-turmerone (1.62 %), curdione (1.60 %) and camphene (1.43 %) respectively. The leaf essential oil was found to be predominant with oxygenated sesquiterpenes (68.20 %). Because of the presence of remarkable phytoconstituents, the leaf essential oil of C. angustifolia would have enough significance in the food and pharmaceutical industries.
