不同产地野菊花挥发油化学成分GC-MS比较分析

Chemical Components Analysis of Essential Oil of Flos Chrysanthemi Indici from Different Regions by GC-MS

采用水蒸气蒸馏法提取野菊花挥发油,并通过气相色谱-质谱联用法(GC-MS)分析其化学成分,用色谱峰面积归一化法计算各组分相对含量,研究不同产地野菊花挥发油的化学成分,为野菊花的开发和临床应用提供依据。结果表明:安微亳州、河南温县、河南南阳、安微黄山、杭州1、河南临颍、河南灵宝、杭州2、广州佛山、江苏无锡10个产地野菊花含有已鉴定出的挥发油成分分别为39个、20个、19个、33个、22个、18个、25个、29个、20个、33个,均含有12种主要相同成分。不同产地野菊花挥发油的主要化学成分相似,但所含种类和含量有明显的差异。

The essential oils of flos chrysanthemi indici from different regions were extracted by steam distillation,the chemical components were analyzed by gas chromatography-mass spectrometer（GC-MS）,and the relative percentage of each component was calculated by normalization method of the chromatographic peak area,so as to provide the experimental evidence for the development and clinical application of flos chrysanthemi indici.The results showed that 39,20,19,33,22,18,25,29,20,33 compounds of essential oils were identified from Bozhou Anhui,Wenxian Henan,Nanyang Henan,Mount Huangshan Anhui,Hangzhou1,Linying Henan,Lingbao Henan,Hangzhou2,Foshan Guangzhou,Wuxi Jiangsu respectively,which contained 12 kinds of the same composition.The main chemical constituents of essential oils of flos chrysanthemi indici from different regions were similar,but there were significant differences in the kinds and contents of essential oils from different regions.
