title: Analysis of volatile components of Curcuma sichuanensis X. X. Chen by gas chromatography-mass spectrometry.
abstract: Volatile components of Curcuma sichuanensis X. X. Chen growing in Sichuan, China, were extracted by steam distillation and analyzed by using gas chromatography and gas chromatography-mass spectrometry. A total of 44 volatile essential oil components were identified in the extract of C. sichuanensis X. X. Chen, representing 87.1% of the total integrated chromatographic peaks. The major compounds were found to be epi-curzerenone (26.9%), germacrone (12.4%), isocurcumenol (9.7%), beta-elemene (6.4%) and curzerene (6.2%). The results of semi-quantitative analysis indicated that levels of total sesquiterpene fraction (85.4%) were more than 55 times higher than those of monoterpene components (1.5%).
