Abstract: The volatile components of China-Hemp leaves were analyzed by simultaneous distillation extraction (SDE) coupled to gas chromatography-mass spectrometry (GC-MS). The effect of extraction time on extraction efficiency using dichloromethane as the extraction solvent was examined. The results indicated an operating time of 4 h proved optimal for SDE. A total of 44 compounds were identified from China-Hemp leaves, accounting for 86.04%, including 7 ketones (4.67%), 2 hydroxybenzenes (6.13%), 4 aldehydes (3.88%), 8 alcohols (15.35%), 13 hydrocarbons (29.40%) and 8 other compounds (25.64%). The prevailing compounds were caryophyllene oxide (14.36%), caryophyllene (8.08%) and α-caryophyllene(7.05%).

Key words: China-hemp, simultaneous distillation and extraction (SDE), gas chromatography-mass spectrometry (GC-MS), volatile components
