重庆缙云山野菊花挥发油化学成分研究

Study on the Chemical Constituents of the Essential Oils from Chrysanthemum indicum Collected in Jinyun Mountains,Chongqing

目的:分析重庆缙云山产野菊花挥发油的化学组成。方法:采用水蒸气蒸馏法提取野菊花挥发油,应用气相色谱-质谱联用仪(GC-MS)对野菊花挥发油的化学成分进行研究。结果:野菊花挥发油经气相色谱法(GC)分离得到92个色谱峰,根据各色谱峰的质谱图,鉴定出69个色谱峰,共66个化学成分,占挥发油总量的90.07%。结论:重庆缙云山产野菊花无论作为药材还是食品原料,质量均佳。比较重庆缙云山产野菊花和文献报道的其他产地的野菊花的挥发油的主要化学成分,发现不同产地野菊花的挥发油组分差异很大。

Objective： To analyse the chemical constituents of essential oils from Chrysanthemum indicum collected in Jinyun Mountains. Methods： The essential oil was extracted by steam distillation and analyzed by GC-MS. Results： The GC chromatogram of the essential oil had 92 peaks among which 69 were identified to be 66 compounds whose relative contents summed to account for 90. 07% of the total essential oil. Conclusion： It indicates Chrysanthemum indicum in Jinyun Mountains is good as medicine or for food. The place of origin has obvious influence on the chemical compostions of Chrysanthemum indicum＇s essential oil.
