摘要
目的:分析、鉴定墓头回挥发油中的主要化学成分并比较其色谱指纹图谱,为建立墓头回药材色谱指纹图谱提供依据。方法:用正己烷超声、索式、回流提取法和超临界CO2萃取法提取墓头回挥发油,采用气相色谱-质谱(GC-MS)联用技术,利用NIST谱库分析、鉴定化学成分。通过测定不同产地的墓头回药材样品,参照相对峰面积分析确定指纹图谱中的共有峰。结果:墓头回挥发油中主要含有丁子香烯、9,12-十八碳二烯酸甲酯、9-十八碳烯酸等30种化学成分,其中可用于指纹图谱定性分析的共有峰11个。结论:色谱指纹图谱共有峰基本可以反映墓头回挥发油的物质组成特性,可用于墓头回药材的鉴别和质量控制。
Objective： To analyze the components and build up the fingerprint of Patrinia Heterophylla （scabra） Bunge （PHB）. Method： The essential oil of PHB was extracted by supersound, recirculation, Soxhlet＇s apparatus and supercritical fluid extraction method and analyzed by gas chromatography-mass spectrometer（GC-MS） with NIST library. The samples of PHB from different place were measured and the common peaks in the fingerprint were confirmed. Results： Thirty compounds in essential oil of PHB were identified and eleven of them will be used as common peaks of the fingerprint to control the quality of PHB. Conclusion： The fingerprint can basically illustrate the composing character of essential oil of PHB and be used to distinguish PHB and control its quality.
