气质联用法分析泽兰不同部位挥发油的化学成分

GC-MS Analysis of Volatile Components in Different Parts of Herba Lycopi

目的:研究泽兰不同部位挥发油化学成分的差异。方法:水蒸气蒸馏法提取挥发油,利用GC-MS计算机联用仪定性分析,按峰面积归一化法求出挥发油中化学成分的百分含量。结果:从泽兰叶挥发油中共分离出63个峰,鉴定出48个化学成分,占其挥发油总量的94.31%;从泽兰茎挥发油中共分离出12个峰,鉴定出9个化学成分,占其挥发油油总量的89.33%。二者均含有反式石竹烯、石竹素、葎草烯环氧化物Ⅱ、Z,Z,Z-1,5,9,9-四甲基-1,4,7,-环十一碳三烯、法尼基丙酮、β-瑟林烯。结论:泽兰茎叶同用入药有其合理性。

Objective：To analyse and compare the chemical components of the volatile oil in different parts of Herba Lycopi.Methods：The volatile oil was extracted by steam-stilling and identified by GC-MS.The percentage composition of volatile oil was calculated by the peak area normalization method.Results：63 peaks were separated and 48 compounds were identified from volatile oils of leaves of Herba Locypi,accounting for 94.31% of the total;12 peaks were separated and 9 compounds were identified from volatile oils of stem of Herba Lycopi,accounting for 89.33% of the total.Both of them included caryophyllene;caryophyllene oxide;12-oxabicyclododeca-3,7-diene,1,5,5,8-tetramethyl-,[1R-（1R＊,3E,7E,11R＊）]-;1,4,7-cycloundecatriene,1,5,9,9-tetramethyl-,Z,Z,Z,-;5,9,13-Pentadecatrien-2-one,6,10,14-trimethyl-;β-selinene.Conclusion：Leaves and stem of Herba Lycopi were used as medicine together,which have its rationality.
