摘　　要： 用超临界二氧化碳和水蒸气蒸馏法提取蛇床子挥发性化学成分,采用毛细管气相色谱-质谱联用技术对2种提取方法所提取的挥发性成分进行分析鉴定。共鉴定出48个挥发性化合物,从水蒸气蒸馏提取物中鉴定出31个化学成分,从超临界二氧化碳提取物中鉴定出21个化学成分,超临界二氧化碳提取方法对蛇床子挥发性成分的提取具有较高的选择性。从蛇床子中检测到蛇床子素、欧前胡素、异虎尔草素、佛手内酯、花椒毒素和花椒毒酚6个香豆素类化合物,并应用质谱学规律对蛇床子中的有效成分蛇床子素的结构进行鉴定和讨论。 The volatile constitutes of Cnidium monnieri were extracted by hydro-distillation and supercritical CO2 extraction. 48 compounds are determined in these extracts,and are identified by capillary gas chromatography combined with mass spectrometric detection. 31 components are identified by hydro-distillation, while 21 components are identified by supercritical CO2 extraction. 6 coumarins including osthole, imperatorin, isopimpinellin, bergapten, xanthotoxin and xanthotoxol are detected in Cnidium monnieri （L.） Cuss. The results show that supercritical CO2 extraction for the volatiles from Cnidium monnieri （L.） Cuss. is more selective. The structure identification of osthole was discussed by mass spectrometry.
