Abstract: Direct distillation extraction method(DDE) and simultaneous distillation extraction method(SDE) were used for extracting the volatile substances of dark green tea. The average oil yields obtained by DDE method and SDE method are 2.02% and 2.34 % respectively. 28 chemical components and 17 chemical components are identified by gas chromatographymassspectrometry(GC-MS ) method respectively. The contents of the identified compounds account for 86.16 % and 90.59 % of the total volatile substances detected respectively.

Key words: dark green tea, volatile substances, gas chromatography-mass spectrometry
