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。

摘  要:
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.
