芹菜叶挥发油化学成分的GC/MS分析

为比较不同地区芹菜叶挥发油的化学组成，采用水蒸气蒸馏方法对产自辽宁3 个不同地区芹菜叶的挥发性成分进行提取，并采用GC-MS 方法对提取的挥发性成分进行鉴定。结果从3 种芹菜叶中一共鉴定出32 种挥发性化学成分，其中鞍山芹菜叶中鉴定出12 种，其含量占挥发油的27.29%，特有成分为β-月桂烯、n-十六酸、9,12,15-十八碳三烯酸等；抚顺芹菜叶中鉴定出16 种，其含量占挥发油的21.78%，特有成分为苯酚、桉叶双烯、5-(1,5-二甲基-4- 己基)-2- 甲基-1,3- 环己二烯等；北票芹菜叶中鉴定出9 种，其含量占挥发油的12.59%，特有成分为桉叶双烯、邻苯二甲酸二丁酯、十八烷等。

GC-MS Analysis of Volatile Components in Celery Leaves

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.
