不同产地野菊花挥发油化学成分比较研究

Chemical Components of Essential Oils From Flos Chrysanthemi Indici in Different Areas

目的 :通过研究分析不同产地野菊花挥发油的成分 ,为野菊花的开发利用提供实验依据。方法 :采用水蒸气蒸馏法提取野菊花挥发油 ,用GC毛细管柱进行分析 ,归一化法测其相对含量 ,并用气相色谱 质谱法对化学成分进行鉴定。结果 :广西野菊花含主要成分 18个 ,广东野菊花 17个 ,湖北野菊花 2 0个。结论 :广西、广东、湖北野菊花挥发油化学成分种类和含量均有明显的差别。

Objective:To provide the foundation for reasonable utilization by analysing the essential oils of Flos chrysanthemi Indici in different areas. Method: The essential oils were extracted by using steam distillation and separated with GC capillary columns. The components were quantitatively determined with normalization method, and were identified with GC MS. Results: 18, 17 and 20 compounds of essential oils from Guangxi, Guangdong and Hubei were identified. Conclusion: There are significant differences among the components and contents of essential oils of Flos chrysanthemi Indici from Guangxi, Guangdong and Hubei.
