水蒸气蒸馏法提取广东刺芫荽挥发油的成分分析

Component Analysis of Volatile Oil Extracted from Guangdong Eryngium Foetiduml by Steam Distillation

目的:分析广东刺芫荽植物的挥发油成分。方法:2020年3月在广州医科大学附属第六医院通过水蒸气蒸馏法提取广东刺芫荽的挥发油成分,采用气相色谱–质谱联用技术对挥发油成分进行分析,并比较其他地区刺芫荽挥发油成分的差异。结果:从广东刺芫荽挥发油中共鉴定出23种化学物,其中含量大于5 %的成分有反式–2–十二烯醛(35.82 %)、2–十二烯醛(24.53 %)、反式–2–十四醛(7.42 %)。结论:提取广东刺芫荽的挥发油成分分析,与云南、海南刺芫荽挥发油成分明显有区别,为今后进一步开发研究广东刺芫荽提供依据。

Objective To analyze the volatile oil components of Eryngium foetiduml plant in Guangdong.Method In March 2020,the volatile oil of coriander kwangtungensis was extracted by steam distillation in Guangzhou University of traditional Chinese medicine.The volatile oil of coriander kwangtungensis was analyzed by gas chromatography-mass spectrometry(GC-MS).The volatile components of coriander kwangtungensis were determined,and the differences of volatile oil between Guangdong and other regions were discussed.Result Identifi ed a total of 23 chemical compounds from the volatile oil of Guangdong Eryngium foetiduml.Among them,the ingredients with content greater than 5%are trans-2-dodecenal(35.82%),2-dodecenal(24.53%),and trans-2-tetradecenal(7.42%).Conclusion The analysis of the composition of the volatile oil of Guangdong Eryngium foetiduml extracted by steam distillation was conducted and compared with the volatile oil components of Yunnan and Hainan Eryngium foetiduml.It showed a signifi cant difference from Eryngium foetiduml in Yunnan and Hainan,which will provide a basis for the further development and research of Guangdong Eryngium foetiduml in the future.
