Abstract:

In order to compare chemical compositions of essential oil in celery leaves from different areas, essential oil in celery leaves from 3 areas in Liaoning province was extracted by using steam distillation method and the compositions of essential oil were identified by gas chromatography-mass spectroscopy (GC-MS). Totally 32 kinds of volatile compounds were identified in celery leaves from 3 areas. A total of 12 kinds of volatile compounds including characteristic compounds of β-myrcene, nhexadecanoic acid and 9, 12, 15-octadecadienoic acid were identified in celery leaves from Anshan, which was accounted for 27.29% of total volatile oil. Sixteen kinds of volatile compounds such as phenol and 5-(1,5-dimethyl-4-hexyl)-2-methyl-1,3-cyclohexadiene as the characteristic components were identified in celery leaves from Fushun, which was accounted for 21.78% of total volatile oil. Nine volatile compounds including special compounds of diene, dibutyl phthalate and octadecane were identified in Baiqiao celery leaves with 12.59% of total volatile oil.

Key words: celery leaves, volatile oil, gas chromatography-mass spectrometry (GC-MS)
