气质联用法分析佩兰和泽兰中挥发油的化学成分

GC-MS Analysis of Volatile Components of Herba Eupatorii and Herba Lycopi

目的:分析比较易混淆品佩兰与泽兰中挥发油的化学成分。方法:采用水蒸气蒸馏法提取佩兰与泽兰中挥发油,运用气相色谱-质谱联用对其化学成分进行分析和鉴定,用气相色谱面积归一化法测定各组分的相对百分含量。结果:经气相色谱-质谱联用技术,从佩兰中分离出44个峰,从泽兰中分离出45个峰,并且确认了所含的化合物。结论:报道了佩兰与泽兰中挥发油的化学成分,二者挥发油的主要成分和含量都有很大区别,因此在临床应用中应当加以区别。

Objective:To analyse and compare the chemical components in the volatile oil of Herba Eupatorii and Herba Lycopi.Methods:The volatile oil was extracted by steam-distilation and analyzed by GC-MS.The relative content of each component was calculated by area normalization method.Results:44 and 45 peaks were isolated from Herba Eupatorii and Herba Lycopi,respectively.All of them were identified.Conclusion:The chemical components of the volatile oil of Herba Eupatorii and Herba Lycopi were reported,There are a ...
